I'm no expert in R but I think that read.table simply will not start a
variable with a numeric. If you really want
the names to be as listed below you can assign them after import by using :
names(mydata) <- c(name, "20_1_TT_Z_e4" "20_2_TT_Z_e4")
name is a factor as far as I can see because that is the default in your
R-profile
See http://finzi.psych.upenn.edu/R/Rhelp02a/archive/98227.html for more details
name's mode is numeric because the underlying form of a factor is numeric.
do str(mydata) for a bit more information

Why name is a factor and numeric? and why I do have X before the
variable namin X20_1_TT_Z_e4? Is it possbile to have it as 20_1_TT_Z_e4 ?
