You've already received several solutions from people more R-savvy
than I, so I will try instead to explain what went wrong with your
code. I will bet you get:
> class(lrates)
[1] "factor"
typeof() can be rather misleading when it comes to factors. They are
represented internally as integers, even you they look like characters
when printed.

If you had attempted the above with as.character(line1, "\\1,") it
might have worked, since you almost certainly were operating on a
factor. The as.character() coercion function will give you the
character labels of the levels of factors.

No problem here. I was wondering if you might be somewhere that uses
the period as a comma and commas as decimal point.
