Hi,

Did you also load the package (you'll need to load it every session
you want to use it)?

## load reshape package
library(reshape)
## now try
merge_all(Br, Ki, Lu, Pr, by="Genes")


If this does not resolve your problem, please run:   sessionInfo()
at your console and report the output (it will tell us information
about your version of R, loaded packages, etc.).

Cheers,

Josh

Hi Josh,
             I thought of giving up and started writing code in excel using
VBA but then I saw ur message and gave a try in R. I got it, the location
from which I am calling the package "plyr" is not working out so
called from
different CRANmirror location and then I was able load the package. now the
merge_all function is working fine. Thanks for your help.
