Plot TPR vs FDR

Plot observed true positive rate (TPR) vs observed false discovery rate (FDR), for given adjusted p-value thresholds and/or as curves traced out by considering all threshold values.

Usage

plot_fdrtprcurve(
  cobraplot,
  title = "",
  stripsize = 15,
  titlecol = "black",
  pointsize = 5,
  xaxisrange = c(0, 1),
  yaxisrange = c(0, 1),
  plottype = c("curve", "points"),
  linewidth = 1
)

Arguments

cobraplot

A COBRAPlot object.

title

A character string giving the title of the plot.

stripsize

A numeric value giving the size of the strip text, when the results are stratified by an annotation.

titlecol

A character string giving the color of the title.

pointsize

A numeric value giving the size of the plot characters.

xaxisrange

A numeric vector with two elements, giving the lower and upper boundary of the x-axis, respectively.

yaxisrange

A numeric vector with two elements, giving the lower and upper boundary of the y-axis, respectively.

plottype

A character vector giving the type of plot to construct. Can be any combination of the two elements "curve" and "points".

linewidth

The line width used for plotting

Value

A ggplot object
