[R] Print and supressing printing in function

2006-09-24 Thread Jonathan Greenberg 
Another newbie question for you all:

In a function, say I have:

countme - function() {
for(i in 1:10) {
i
}
}

How do I get R to print i as it runs (e.g. By calling countme) -- right
now it seems to supress most output.  On a related note, my program uses
remove.vars, which always prints its output -- how to I *supress* that
output?

Thanks!

You need to explicitly print() the value. Thus:

countme - function() {
for(i in 1:10) {
print(i)
  }
}

 countme()
[1] 1
[1] 2
[1] 3
[1] 4
[1] 5
[1] 6
[1] 7
[1] 8
[1] 9
[1] 10

HTH,

(Answering remove.vars question)

Please read ?remove.vars. (You neglected to mention this function is 
part of the gdata package.) There is an info argument you want to set 
to FALSE.

Thanks for noticing my oversight Sundar.
