You could set `as.is = TRUE' when running read.table(), as the help

I have done a read.table on a data file with the aim of extracting
subsets of the data eg
    table[table$desc = 'result1',]

How can I convert $desc to a character type? At present it is seen by
typeof() as an integer.
How can I do the equivalent of 

    table[table$desc = 'result1' && table$amt > 20, ]

Thanks,
Rory
