plot.density.matrix: Density plots for every column in a matrix

In drmjc/mjcgraphics: mjc's graphics library

Description

Generic function to plot the columns of a matrix/data.frame as overlayed density plots.

Usage

  plot.density.matrix(data, legend = FALSE, add = FALSE,
    main = "Density Plot", ylim = NULL, xlim = NULL,
    xlab = "Expression Level (Log2)",
    ylab = "Probability Density", col = NULL,
    auto.log2 = TRUE, lty = NULL, legend.cex = 0.5, ...)

Arguments

data	a matrix or data.frame of values
legend	logical: add a legend to the plot?
add	logical: if TRUE, add to an existing plotting device, else create a new plotting device
main	the plot title
ylim	the y-axis limits. if NULL, this is auto-calculated
xlim	the x-axis limits. if NULL, this is auto-calculated
xlab	the x-axis title
ylab	the y-axis title
col	the colours of each density curve, which are recycled if necessary. if NULL, the standard colours 1:8 are used.
auto.log2	logical: automatically log-base-2 transform
lty	the line type for each density play. if NULL, line types 1:ncol(data)
legend.cex	the character expansion of the legend. default=0.5
...	arguments passed to lines
