Dear R-users,

I'd like to create filenames in a mask "file000.dat" numbered from 1 to e.g.
123. The last problem I'm dealing with is creating the sequence of numbers
with equal length, i.e. 001, 002,.... 023, 024,.... 122, 123.

The closest I got is by a repetition:

Sequence <- c(1:123)
for(i in c(1:length(Sequence))) {
print(
    paste(rep("0",
max(nchar(as.character(Sequence)))-nchar(as.character(Sequence[i]))),
    as.character(Sequence[i]),
    sep=""))
}

where pasting "0"-replication the missing-times I 'm possibly creating the
desired output. It's just that rep()'s output is not a vector and not
subsequent atoms. and gives "02" and "02" instead of "002".

Any idea hot to correct the function above or suggestions on
file000.dat-mask filename, please?

Thank you for your time.
M
