R help - Aug 2006 - how to read just a column

Hi,
how can I read, using for example read.table() or scan(), just one
column from a text file that has more columns without any header?

Thanks, bye.

you can read them all in and delete the ones you don't want.  Or check
out 'what' on 'scan' or colClasses on 'read.table'

afaik, you have to read all the table
and then you select the column you want.
eg read.table(blabla)[3] to get the 3rd column.

You can read partially rows (see nrows) but not columns.
Please somebody correct me if I am wrong.

(Of course a trick could be to transpose your table
before writing it, etc)
