Package 'HubPub'

Title: Utilities to create and use Bioconductor Hubs
Description: HubPub provides users with functionality to help with the Bioconductor Hub structures. The package provides the ability to create a skeleton of a Hub style package that the user can then populate with the necessary information. There are also functions to help add resources to the Hub package metadata files as well as publish data to the Bioconductor S3 bucket.

Add a hub resource

Description

This function adds a hub resource to the AH or EH package metadata.csv file. It can be used while creating a new hub package or for adding data to an existing package.

Usage

add_resource(package, fields, metafile = "metadata.csv")

Arguments

package

A character(1) with the name of an existing hub package or the path to a newly created (not yet submitted/accepted) hub package.
fields

A named list with the data to be added to the resource. Elements and content of the list are described in ?hub_metadata.
metafile

A character(1) with the name of the metadata csv file. The default file name is 'metadata.csv'.

Value

Path to metadata file where resource was added

Examples

## create a mock package
pkgdir <- tempdir()
create_pkg(file.path(pkgdir, "recordPkg"), "ExperimentHub")

## create a metadata record
meta <- hub_metadata(
    Title = "ENCODE",
    Description = "a test entry",
    BiocVersion = "4.1",
    Genome = NA_character_,
    SourceType = "JSON",
    SourceUrl = "https://www.encodeproject.org",
    SourceVersion = "x.y.z",
    Species = NA_character_,
    TaxonomyId = as.integer(9606),
    Coordinate_1_based = NA,
    DataProvider = "ENCODE Project",
    Maintainer = "tst person <[email protected]>",
    RDataClass = "data.table",
    DispatchClass = "Rda",
    Location_Prefix = "s3://annotationhub/",

## add the record to the metadata
add_resource(file.path(pkgdir, "recordPkg"), meta)

Create a Bioconductor Hub package

Description

This function creates the skeleton of a package that follow the guidelines for Bioconductor type packages. It is expected of the user to go through and make any necessary changes or improvements once the package begins to take shape. For examples, the DESCRIPTION contains very basic requirements, but the developer should go back and fill in the 'Title:' and 'Description:' fields.

Usage

create_pkg(package, type = c("AnnotationHub", "ExperimentHub"), use_git = TRUE)

Arguments

package

A character(1) with the path of the package to be created.
type

A character(1) to indicate what type of hub package is to be created. Either AnnotationHub or ExperimentHub are acceptable.
use_git

A logical(1) indicating whether to set up git using usethis::use_git(). Default is set to TRUE.

Value

Path to package location

Examples

fl <- tempdir()
create_pkg(file.path(fl, "tstPkg"), "AnnotationHub")

Create and validate metadata

Description

This functions makes a list of values that can be used to add as a resource to a 'metadata.csv' file in a Hub package. The type of each argument indicates the expected value, e.g., Title = character(1) indicates that it is expected to be a character vector of length 1. See individual parameters for more information.

Usage

hub_metadata(
  Title = character(1),
  Description = character(1),
  BiocVersion = package_version("0.0"),
  Genome = character(1),
  SourceType = character(1),
  SourceUrl = character(1),
  SourceVersion = character(1),
  Species = character(1),
  TaxonomyId = integer(1),
  Coordinate_1_based = NA,
  DataProvider = character(1),
  Maintainer = character(1),
  RDataClass = character(1),
  DispatchClass = character(1),
  Location_Prefix = character(1),
  RDataPath = character(1),
  Tags = character()
)

Arguments

Title

character(1) Title for the resource with version or genome build as appropriate.
Description

character(1) Description of the resource. May include details such as data type, format, study origin, sequencing technology, treated vs control, number of samples etc.
BiocVersion

The two-digit version of Bioconductor the resource is being introduced into. Could be a character vector "4.1" or an object created from package_version(), e.g., package_version("4.1").
Genome

character(1) Name of genome build.
SourceType

character(1) Form of originial data, e.g., BED, FASTA, etc. getValidSourceTypes() list currently acceptable values. If nothing seems appropriate for your data reach out to [email protected].
SourceUrl

character(1) URL of originial resource(s).
SourceVersion

character(1). A description of the version of the resource in the original source. Since source version may not follow R / Bioconductor versioning practices, this field is not restricted to a package_version() format.
Species

character(1) Species name. For help on valid species see getSpeciesList, validSpecies, or suggestSpecies.
TaxonomyId

integer(1) NCBI code. There are checks for valid taxonomyID given the Species which produce warnings. See GenomeInfoDb::loadTaxonomyDb() for full validation table.
Coordinate_1_based

logical(1) are the genomic coordinates in the resource 0-based, or 1-based? Use NA if genomic coordinates are not present in the resource.
DataProvider

character(1) Provider of original data, e.g., NCBI, UniProt etc.
Maintainer

character(1) Maintainer name and email address, ⁠A Maintainer <URL: a. [email protected]>⁠.
RDataClass

character(1) Class of derived R object, e.g., GRanges. Length must match the length of RDataPath.
DispatchClass

character(1) Determines how data are loaded into R. The value for this field should be Rda if the data were serialized with save() and Rds if serialized with saveRDS. The filename should have the appropriate rda or rds extension.

A number of dispatch classes are pre-defined in 
AnnotationHub/R/AnnotationHubResource-class.R with the suffix `Resource`.
For example, if you have sqlite files, the AnnotationHubResource-class.R
defines SQLiteFileResource so the DispatchClass would be SQLiteFile. 
Contact [email protected] if you are not sure which class to 
use. The function `AnnotationHub::DispatchClassList()` will output a 
matrix of currently implemented DispatchClass and brief description of 
utility. If a predefine class does not seem appropriate contact 
[email protected].
Location_Prefix

character(1) URL location of AWS S3 bucket or web site where resource is located.
RDataPath

character(1) File path to where object is stored in AWS S3 bucket or on the web. This field should be the remainder of the path to the resource. The Location_Prefix will be prepended to RDataPath for the full path to the resource. If the resource is stored in Bioconductor's AWS S3 buckets, it should start with the name of the package associated with the metadata and should not start with a leading slash. It should include the resource file name. For strongly associated files, like a bam file and its index file, the two files should be seperates with a colon :. This will link a single hub id with multiple files.
Tags

character() Zero or more tags describing the data, colon : separated.

Value

None

Examples

hub_metadata()

tst <- hub_metadata(
    Title = "ENCODE",
    Description = "a test entry",
    BiocVersion = package_version("3.9"),
    Genome = NA_character_,
    SourceType = "JSON",
    SourceUrl = "https://www.encodeproject.org",
    SourceVersion = package_version("0.0"),
    Species = NA_character_,
    TaxonomyId = NA_integer_,
    Coordinate_1_based = NA,
    DataProvider = "ENCODE Project",
    Maintainer = "tst person <[email protected]>",
    RDataClass = "data.table",
    DispatchClass = "Rda",
    Location_Prefix = NA_character_,
    RDataPath = "ENCODExplorerData/encode_df_lite.rda",
    Tags = c("ENCODE", "Homo sapiens")
)

A function that publishes resource to the hub S3 bucket

Description

This function uses functionality from the aws.s3 package to put files or directories on the Bioconductor's test hub S3 bucket. The user should have already contacted the hubs maintainers at [email protected] to get the necessary credentials to access the bucket. These credentials should be delcared in the system environment prior to running this function.

Usage

publish_resource(path, object, dry.run = TRUE)

Arguments

path

A character(1) path to the file or the name of the directory to be added to the bucket. If adding a directory, be sure there are no nested directories and only files within it.
object

A character(1) to indicate how the file should be named on the bucket.
dry.run

A boolean to indicate if the resource should in fact be published. The defalut is TRUE, meaning the resource won't be published.

Value

None

Examples

pkgdir <- tempfile()
fl1 <- file.path(pkgdir, "mtcars1.csv")
dir.create(dirname(fl1), recursive = TRUE)
write.csv(mtcars, file = file.path(fl1))
fl2 <- file.path(pkgdir, "mtcars2.csv")
write.csv(mtcars, file = file.path(fl2))
publish_resource(pkgdir, "test_dir")

fl3 <- file.path(pkgdir, "mtcars3.csv")
write.csv(mtcars, file = file.path(fl3))
publish_resource(fl3, "test_dir")
