[R] "With" question

[David Arnold]

All,

Trying to avoid using attach and detach while teaching class in Intro Stats.

data=read.delim("dataset1.dat",header=TRUE)
with(data,{
  sort(age)
  length(age)
  (age[10]+age[11])/2
})

However, this code only produces output for the last line between the curly
braces. Granted, as we type the lines in one at a time and execute the code,
we'll see each output. And, we can fix the problem by adding a print to each
line.

Wonder if there are any other suggestions?

David
