[R] how to avoid add 'X' before numeric colnames when read.table

This really depends on where the 'X' is coming from, which you did not tell us (see the posting guide).

For example, if the 'data.frame' function is the one adding the 'X', then you can use the 'check.names' argument to prevent the addition (or you can use data.frame with the argument to explicitly create your own data frame with the names you want, then pass that to the function that is doing the conversion currently).

If a different function is adding the 'X', then look at the help page for that function, or give us more to go on.

Hope this helps,
