plotScatter {Starr} | R Documentation |
A matrix of pairwise scatterplots is created. The lower panle shows the correlation of the data.
plotScatter(eSet, density=F, cluster=T, sample=NULL, cex=1)
eSet |
an ExprssionSet or matrix, containing the data |
density |
if TRUE, a density scatter plot is plotted. This plot shows the density of the data. |
sample |
An integer, indicating the number of subsamples to take for the density scatterplot. This is only recommended if the data is very large, as the density computation takes some time. |
cluster |
if cluster=T, the experiments are clustered and similiar experiments are plotted together. |
cex |
see ?par |
