Hello R users,

Good day!!

I was wondering if there is a way in R to read in a particular column from a tab-delimited file, edit it and write it back into the file with all other columns intact. When I say edit I mean just replacing all the values in that column.
I know to read a particular column from a file using colClasses option in read.delim() function.
Is there any such option to write out a column into an already existing file using write.table() function ??

Thanks for your time
