Question

When I use R, I try to extract specific rows which have some specific strings in one column. The data structure as following

ERC1    20679  14959  9770  RAB6-int         


        

Answer 1

Assuming that your data frame is df:

df[grep("^RAB6", df$column),]

If not all values start with RAB6 remove the^.
