HI, I have a dataframe like this: name ? ?type A ? ? ? ? ?t1 B ? ? ? ? ? t2 C ? ? ? ? ?t1 D ? ? ? ? ? t1 E ? ? ? ? ? t3 F ? ? ? ? ? ?t2 how can I have a "sub dataframe" based with the column "type" like this: (for type = t1) name ? ?type A ? ? ? ? ?t1 C ? ? ? ? ?t1 D ? ? ? ? ? t1
Let's say your data.frame is stored in a variable named "df": R> subset(df, type == 't1') Read the help files: R> ?subset Also take a look at ?split -steve
