Function to plot correlation of different samples
Description
This function can be used to visualise the (rank) correlation in expression data between different samples or sample groups.
Usage
1 2 
Arguments
eset 
object of class 
samples 
which samples' expression shall be correlated to each
other; either a numeric vector of sample numbers in the

grouping 
an optional factor vector defining if the correlation should be assessed between groups of samples, rather than individual samples. If two or more samples are assigned into the same group, the mean over these samples' expression values is taken before computing correlation. Default NULL means assess correlation between individual samples only.

Value
The function only returns NULL (invisible). The function is called for its sideeffect producing the pairs plot.
