I'm pretty new with the R language. I'm just trying to get familiar with R and wrote a script in gedit (should I use emacs instead?),

x <- [10.4  5.6  3.1  6.4 21.7]
y <- [12,5.6, 7.2, 1.0, 9.3]

then I went to the command window in the terminal (I'm using unix) to run
this with source("name_of_file"), but it doesn't work. Shouldn't a plot
come up automatically when I run it? What am I doing wrong? It knows what x
and y is, but I don't get an error of what might be wrong.

> source("name_of_file")
> x
[1] 10.4 5.6 3.1 6.4 21.7


Maybe you should use interactive prompt to get feed back of your syntax. Even you had two different ways in your arrays, both the prompt did not accept.

This seemed to work:

> 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)
