There might be an x in your R session, but not from that script. Try
it by pasting
those three lines at the command line:
> x <- [10.4 5.6 3.1 6.4 21.7]
Error: unexpected '[' in "x <- ["
> y <- [12,5.6, 7.2, 1.0, 9.3]
Error: unexpected '[' in "y <- ["
> plot(x,y)
Error in plot(x, y) : object 'x' not found
You should get an error message when you try to source the script, I
would think.
Try instead:
x <- c(10.4, 5.6, 3.1, 6.4, 21.7)
y <- c(12, 5.6, 7.2, 1.0, 9.3)
plot(x, y)
and rereading your introductory materials.
If that still doesn't work then we'll need more information, like OS
and version of R.
