Hi. i have a data, and there is 3 columns, Month, Year and Total. and there is over 1000 rows for them because there is 87 years data for every month, so there is month from Jan-Dec, and year from 1900-1987, so i was wondering if i would want to make 12 groups (Jan,Feb.......,Dec), and put each year's total into the corresponding month (so every month group will have 88 values of total) how can i do that? many thanks. -- View this message in context: http://www.nabble.com/grouping-data-together-tp20389726p20389726.html Sent from the R help mailing list archive at Nabble.com.
