Hi all, Is there an equivalent to the general * operator in R, where * can represent any character? I have a dataset, one column being date, date ranging between April-September, 97-06. I would like to be able to acquire the data for a specific month, say September, so that I can take average temperatures for the month, etc. I thought I would be able to do something like data.s1 <- subset(data,date=="**-Sep-**") data.s1 but when I do data.s1 I get "0 rows or 0-length row.names". Any idea of a simple way I can perform this task? All dates are in the form xx-xxx-xx, EG 30-Sep-06. Thanks for any assistance.
