intersection

Given a mergeExpressionSet, this function returns a single ExpressionSet.  Only genes common to all studies are included.  Expression data for all studies sits side by side in the 'exprs' slot. The 'notes' slot is used for inormation about the study identity of each sample.

manip

The functions in this R extension are intended for
cross-study comparison of gene expression array data. Required
from the user is gene expression matrices, their corresponding
gene-id vectors and other useful information, and they could
be 'list','matrix', or 'ExpressionSet'. The main function is 'mergeExprs'
which transforms the input objects into data in the merged format,
such that common genes in different datasets can be easily found.
And the function 'intcor' calculate the correlation coefficients.
Other functions use the output from 'modelOutcome' to graphically
display the results and cross-validate associations of gene
expression data with survival.
