Subject: how to create many variables at one time?

Hi Manli,
you may consider structuring your data in some appropriate form like
data.frame or list. Its often not the best way holding information
separated in many variables.
But if you *really* want to create 100 separate variables, something like
for (i in 1:100) assign(paste("X",i,sep=""), some_values)
will do the job.
