In elqumsan/RNAseqMVA: Application of Multivariate Analysis methods to RNA-seq Data

Description

Draw a barplot with the number of million reads per sample

Usage

LibsizeBarplot(
  counts,
  sample.labels = colnames(counts),
  sample.colors = NULL,
  main = "Library sizes",
  xlab = "libsum (Million reads per sample)",
  cex.names = 1,
  lmargin = cex.names * max(nchar(sample.labels))/2.5 + 5,
  ...
)

Arguments

counts	a count table with 1 row per feature and 1 column per sample
...	additional parameters are passed to barplot
sample.labels=colnames(counts)	sample labels (displayed as y legend)
sample.colors=NULL	sample-specific colors (e.g. reflecting conditions)
main="Library	sizes" Main title for the plot
xlab="libsum	(Million reads per sample)" X axis label
plot.file=NULL	Path of a file to store the figure (pdf format).
fig.format="pdf"	File format (only used if plto.file is defined)
cex.names=1	fondt size for sample labels
lmargin=cex.names*max(nchar(sample.labels))/2.5+5	Adapt margin to the label sizes
width=7	width of the plot file
height=length(sample.labels)/3+2	height of the plot file (if not specified, will be adapted to the number of samples)
