[R] cat and positioning of the output

[J?rn Schulz]

Hello R users!

I like to use cat in a loop. I know, loops are not the best way in R ... but
my question: It is possible to overwrite the expression "Reading row: i" in
each iteration of the loop (print out in the below loop on the screen) or
more particulary to overwrite the counter "i".

for(i in 1:header$M){
   cat("Reading row: ", i)
   SparseIndex[[i]] <- readBin( con, integer(), n=MIndexNumber[i], size=4 )
   SparseSignal[[i]] <- readBin( con, numeric(), n=MIndexNumber[i], size=4 )
}

Many thanks
J?rn Schulz.
