[R] convert 1, 10, and 100 to 0001, 0010, 0100 etc.
Hi, Is there an easy way to convert numbers into a form such that they all have the same number of digits? e.g.: 1, 10, and 100 ...become... 0001, 0010, 0100 etc. I ask because I am producing a large number of files that need to sort consistently by filename. Currently I get this kind of sorting: filename1 filename10 filename11 filename12 filename13 filename14 filename15 filename16 filename17 filename18 filename19 filename2 filename20 filename21 ...etc.. which is annoying. Ideally I'd have: filename0001 filename0002 filename0003 filename0004 filename0005 filename0006 filename0007 filename0008 filename0009 filename0010 filename0011 ...etc.. Basically I want to produce strings like 0010 without an elaborate hack. Thanks! Nick -- Nicholas J.
