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,...){
