Data transformation

[Mariusz <setesh@gazeta.pl>]

Hello,

I am just starting with s-plus and have the following problem.
I have some data in file with columns: name, value, data,...
I read it into R by using read.table.

All I need is just a function which changes all non-numerical
characters in 'value' column into specified numeric value(e.g. 0). I
have tried something like:
myData$value[!is.numeric(myData$value)] <- 0
and several other combinations, but with no success :(. Any hints?
