Hi
I have a data frame as below
t1 t1 t3 t4 len1 AA AA PP AP len2 FALSE AA PP MM len3 PP AA AA AP len4
PP AM MP PP len5 AA FALSE AP PP len6 PP AA AA AA
I am having trouble extracting only those rows which have "PP" in the first
column but AA or FALSE or all any other value but not PP in rest of the
columns.
