Hi,
I am trying to color the data points on my boxplot but I only get the
default black.
You mean the outlier points?
Not sure why.  Any ideas?
Look at:

? bxp

... and try ,,,  outcol="red"
Thank you,
Mark

Here is my code.

dat.g100 <- dat.sg[100,] # selected gene (row) from a dataframe of
37 columns

d1 <- as.matrix(dat.g100[,1:18]) # subset 1

d2 <- as.matrix(dat.g100[,19:37]) # subset 2

# boxplots

par(mfrow=c(2,1))

boxplot(d1, cex=0.3, col="red",
las=2,cex.axis=0.6,ylab="intensity",main="B cells: germinal center ? gene
100")

boxplot(d2, cex=0.3, col="blue",
las=2,cex.axis=0.6,ylab="intensity",main="B cells: activated ? gene 100")
