Details

This function allows the user to extract various elements from a different analytical object class which in turn, creates a temporary data frame to plot the necessary ggplot aesthetics. In order for this function to work, RNA seq experiments must have multiple factors (i.e. two treatments and a control) and levels including treatments and controls. By having the recommended criteria, this function will extract the necessary data dependent on the analysis performed. Data points with "extreme" values that exceed the default viewing frame of the plot will change character classes (i.e. points of interest a substantially large log fold change).

  "edger"), padj = 0.05, y.lim = NULL, lfc = NULL, title = TRUE,
  legend = TRUE, grid = TRUE, highlight = NULL, data.return = FALSE,
  xaxis.text.size = 10, yaxis.text.size = 10, xaxis.title.size = 10,
  yaxis.title.size = 10, main.title.size = 15, legend.text.size = 9)

Arguments

`data`	a cuffdiff, DESeq2, or edgeR object.
`d.factor`	a specified factor; for use with DESeq2 objects only. Defaults to `NULL`
`type`	an analysis classifier to tell the function how to process the data. Must be either `cuffdiff`, `deseq`, or `edgeR`.
`padj`	a user defined adjusted $p$ -value cutoff point. Defaults to `0.05`.
`x.lim`	set manual limits to the x axis. Defaults to `NULL`.
`lfc`	$log$ fold change level for setting conditonals. If no user input is added (`NULL`), value defaults to `1`.
`title`	show title of plot. Defaults to `TRUE`.
`legend`	shows legend of plot. Defaults to `TRUE`.
`grid`	show major and minor axis lines. Defaults to `TRUE`.
`counts`	displays the number of differentially expressed genes for each treatment comparison. Defaults to `TRUE`.
`data.return`	returns data output of plot if set to `TRUE`. Defaults to `FALSE`.
`xaxis.text.size`	change the font size of the `x`-axis text. Defaults to `9`.
`yaxis.text.size`	change the font size of the `y`-axis text. Defaults to `9`.
`xaxis.title.size`	change the font size of the `x`-axis title text. Defaults to `10`.
`yaxis.title.size`	change the font size of the `y`-axis title text. Defaults to `10`.
`main.title.size`	change the font size of the plot title text. Defaults to `15`.
`legend.text.size`	change the font size of the legend body text. Defaults to `9`.
`facet.title.size`	change the font size of the facet wrap title text. Defaults to `10`.
