Hi Manisha -- this is a bioconductor package, so ask on the Bioconductor mailing list. The 'exprSet' class is quite old, and has been replaced by the 'ExpressionSet' class. Update your venison of R and Bioconductor (http://bioconductor.org/download). Then evaluate the commands
> library(Biobase) > openVignette() and read the first vignette 'Biobase - An introduction to Biobase and ExpressionSets'.
