R help - Oct 2005 - Problem building/checking library that requires input from user

Hi all,

I've got a package i've written that i am trying to check, build, and 
install. This is my 1st time doing this, so apologies in advance... ;)

The package that I've written requires input from the user. It needs to know
sample sizes and then runs some calcs, (sample sizes are just integers), and 
it gets this info from the user as

num_reps <- readline("How many reps do you have... ")

num_reps <- as.integer(num_reps)

and then loops

for(i in 1:num_reps)
{
      #code
}


HOWEVER, I get this error msg when trying to check/build/install:

Error in 1:num_con_biol_reps : NA/NaN argument

Presumably this is because R thinks the variable is never initialized before 
i try to use it as a loop limit...

Anyway around this?? I tried initializing the num_reps variable in the code 
before the readline, but get the same error...


Thanks very much in advance,
Ken

Either use \dontrun in a \examples{} section of a help page (see Writing 
R Extensions), or something like

num_reps <- if(interactive()) readline("How many reps do you have...
") else 500

Thanks, Dr Warnes & Prof Ripley...

However, upon following the instructions below, I'm getting syntax errors on
the line that has \dontshow...below is my code...I get the same error if i 
omit the first block and just try \dontrun...

\dontshow{
num_reps <- 10
}

\dontrun{
num_reps <- readline(""How many reps do you have... ")
num_reps <- as.integer(num_reps)
}


could this have anything to do with it running on OS X 10.3 ?? (long 
shot...but i'm thoroughly lost)..

thanks again,
ken

It was in a plain R file...I did not interpret the word 'example' in
your
email as I should've...

So, i've been able to fix the num_reps variable problem - thanks!!
