Hi I have dataframe with different plot numbers in and different subplots as letters at the end of the plot number i.e. 1a, 1b 2-1a etc. I want to delete all rows that end in a specific letter eg...
treat<-c("1a","1b","1c","2a","2b","2c","2-1a","2-1b","2-1c") a1<-1:9 b1<-9:1 d1<-data.frame(treat,a1,b1) How do I remove all rows where treat ends in "c" ? I have tried the usual ways of deleting rows but nothing works.
