[R] (no subject)

Alternatively if you want to avoid using lists, you can create the variables like this:

for (i in 1:10) assign(paste("x",i,sep=""),i^2)

and view them subsequently like this:

for (i in 1:10) print(get(paste("x",i,sep="")))

- This is FAQ 7.23 (see the FAQ's, please).
- I'd suggest to use a list instead of a couple of different objects.
- See ?assign for more details related to your question:
  assign(paste("variableName", x, sep=""), c(2,3,4))
