Not sure what you wanted to do.Note that you have "test'txt" and "log.txt"
in your code. Using only "test.txt", the following worked fine for me:
letters[1:5]->x
logf<-"test.txt"
cat('%%\n',file=logf)
catf<-function(x,...,logfile='test.txt', append=TRUE){ cat(x,'\n',
Your call to catf in testit is after the return, so it is never called.
FWIW my antibugging strategy (and readability strategy) is to never use the
return function... I structure my logic to end up at the end with my desired
function result in a variable and I simply put that variable on the
testit<-function(x,...){
paste0('this is x: ',x)->y
return(y)
catf("++test=",...)
}
You return from the function before calling catf(). Remove the 'return(y)'
and make 'y' the last expression in the function.

Hi List,
I am trying to write unsuccessfully to a logfile with cat. Here my example code:
letters[1:5]->x
logf<-"test.txt"
cat('%%\n',file=logf)
catf<-function(x,...,logfile='log.txt', append=TRUE){ cat(x,'\n', file=logfile,
append=append)}
testit<-function(x,...){

It is clear for me now the use of cat(). As Steve pointed out in his
mail, I've failed at providing an example, one of the rules of thumb of
this list!
Thanks, Steve,

It seems like you're asking to use cat() for something it's not meant
to do. cat() is generally used to write output, either to the screen
or to a file.
Sorry for not adding an example to my first post! And yes, I was trying
to use it for something it
