[R] variables in object names

[Sarah Goslee]

Hi Ken,

Not quite the way you're thinking about it, but yes, there is,
and it is very useful. See ?get for more information, but here's
the basics:

for(i in 2:5) {
  thismodel <- get(paste("model", i, sep=""))
  rsq <- c(rsq, summary(thismodel)$r.squared)
}


Also see ?assign for the opposite effect.
