converting numeric data to charactersI had to import several data type columns into jmp as numeric (coded 1-4, for example). I'd like to convert the numbers to more meaningful characters. For example in a column labeled "SITE", I'd like to make the following change:
1==DL
2==SL
3==KA
4==MP
Should this be done in the formula editor with a series of IF statements, or is there a cleaner way. If I use IF statements, then how can I delete the original numerically coded columns. Thanks in advance.Re: converting numeric data to charactersHow about column, recode (the menu option, not a formula). This can either exchange the values in place, in another column, or in a formula.Re: converting numeric data to characters

style="font-family: Arial;">I think the "match" function
would work best. Just create a new column called SITE, and
use the following formula (replacing :Column 1 with your reference
column).
Match( :Column 1,
style="font-family: Arial;">
1, "DL",
2, "SL",
3, "KA",
4, "MP"
);

If you want to make it a script, do this:
