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] 134 213
.............
it uses level number instead of its content like "P05761". What's wrong
with it? how can I get its content instead of level number? I can use some
dirty ways to do that but I didn't understand why.
