Dear Prof. Ripley,
Would it be possible to make sprintf accept vector arguments? I.e. allow expressions like sprintf("%04d", 1:3) to produce something like what currently needs to be done via sapply(1:3, function(i) sprintf("%04d",i))
I have thought about this, but it is not really clear what the right thing would be here with multiple arguments. What should
sprintf(("%04d %s", 1:3, "abc")do? Produce a character vector of length 1 or 3? If of length 1, "0001 0002 0003 abc" or "0001 2 0003 abc"?
I guess the most R-like thing would be to recycle args to the length of the longest and then use them in parallel, but that can be done fairly easily by *apply.
