R help - Sep 2013 - "With" question

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

You seem to be applying the syntax for the within function to the with function.
You should compare the documentation for them and choose your approach
accordingly.
Also once inside a code block of any type, simply typing a variable name no
longer prints it, so you need to use the appropriate function (print or cat).
