[R] Executing R scripts from another R script

[Sergey Goriatchev]

Sorry everyone

Disregard this email.
I found the problem.
I have xlsReadWritePro loaded automatically at start of R.
Then I load package gplots, which also loads gdata
gdata masks function read.xls() from xlsReadWritePro and that causes
all the problems.

Regards,
Sergey
