Dear all,
 
I would like to know how can I retrieve a data.frame without the columns that have a partial match name. Let´s say that I have a data.frame with 200 columns and 100 of them have the name "StartX", with X being the unique part for each column name. I want to delete all columns that have the name starting with "Start". I´ve tried to do this but it doesn´t work:
 
> DATA_OK <- DATA[,-match(("Start*"),names(DATA))]
> dim(DATA_OK)
NULL

 
Thanks in advance.
Best regards
