Hi Kenny,

Take a look at parse() if you want it do your way, but consider the 
following much better way. Read the files into a list first not in 
seperate R objects, something like:

list_tables = lapply(list.files(), read.table)
?lapply

and plot:

for(tab %in% list_tables) plot(tab)

cheers,
Paul
