Hi
I have a tab-separated data set which contains a number of dates entered as strings. Converting the strings to dates is no problem using the 'date' function, but the new variable is added to the end of the data set. For example, if I have a data set that has the following variables
id stringdate1 info1 stringdate2 info2
(where the stringdates are dates encoded as strings) and I cast the strings into real dates (and delete the strings), I end up with a data set that looks like
id info1 info2 realdate1 realdate2
Not a problem for a data set with five columns, but real data sets are much broader. In any case, it would be nice to keep all the '1' data items together etc.
Can I convert data 'in place' or move columns back to their 'original' positions?
Many thanks.
Regards
Joseph
