R help - Mar 2004 - data frame output

Hello list,

Is there a way to *not* supress leading zeros when printing (to the
console window or to a file) a dataframe?

Thanks,

If you mean via print() or autoprinting, no.
I am not sure why you would want to do this, but it seems that using
format() and then gsub should work.  For example

library(MASS)
fh <- format(hills)
fh[] <- lapply(fh, function(x) gsub(" ", "0",
as.character(x)))
fh
                 dist climb    time
Greenmantle      02.5  0650 016.083
Carnethy         06.0  2500 048.350
Craig Dunain     06.0  0900 033.650
Ben Rha          07.5  0800 045.600
Ben Lomond       08.0  3070 062.267
...

Yes, e.g. use

  formatC(..., format = "f")

to produce a character matrix and write() that to your file.
