[R] Importing a dataset

[Gabor Csardi]

I don't know a way of loading parts of an .RData file either,
but another solution is to use the envir argument of load to
load the data into a new environment:

> x <- 1
> y <- rnorm(3)
> save.image("tmp.RData")
> rm(x)
> rm(y)
> load("tmp.RData", env <- new.env())
> get("x", env)
[1] 1
> get("y", env)
[1] -0.1105102  0.6923334  1.5506114
> rm(env)
