for example: I have a data frame. data$V4 returns: ..... [6936] P05796 P11096 P76174 P04475 P18775 [6941] P33225 P76387 P76388 P76388 P09375 [6946] P15300 P15723 1375 Levels: O50190 O65938 O69415 P00274 P00363 P00364 P00370 P00373 ... Q9AJ15 data$V5 returns something like data$V4 I want to cbind this two columns, so I use new <- cbind(data$V4,data$V5) I expect it to return something like: [1] P05761 P11986 [2] ....... however it returns [1] 215 434 [2]...
