Hello. I'm trying to run a series of commands in two different datasets. For
make it efficient I want to make a loop for it. Until now the only command
for loops i found it's the for() command it's only for series of numbers and
not a series of strings,
What gave you that idea? A for loop can loop over any vector.
witch it's what i'm needing. It would be something
like this
for(i in dataset1 dataset2) {
Use
for (i in c("dataset1", "dataset2"))
to set i to each of those strings in turn.
i <- read.dta("dataset1.dta")
ls()
summary(i)
str(i)
attach(i)
}
None of the above will work, but it's almost all a bad idea anyway.

I hope the idea it's clear. I'm using 2.9.1 Windows Version of R.
Thanks.
