[R] Bar plot

[Peter Ehlers]

Here is a simple 3-step solution:

1. type ?barplot
2. find the section labelled 'Arguments'
3. carefully read what each argument means/does

Voila, problem(s) solved.

(It was good to include some data, but not so good
to say that title(...) is giving "an error". No need
to be secretive about the error; just say what it was.)
