[R] graphics question

[Paul Lemmens]

Hi

after browsing the documentation and web, I'm completely lost as how to 
create the graph I describe below (as best as I can).

I've got 3 pairs of average response times: (390,396), (416, 421), 
(406,415). Each of these pairs represents a level of a certain factor 
(let's call it 'loc'), namely (in the same order), levels "c", "nc" and 
"ni". Within a pair, the first value belongs to the level "sc" of the 
factor 'cat'; the second value belongs to the level "oc".

The graph I'm looking for has on the y-axis the RT values (in ms), so this 
should range from 350 - 450. On the x-axis I want two ticks for each level 
(sc and oc) of the 'cat' factor. In the plot, three lines should be 
displayed, for each level of the factor 'loc', pref. including a legend.

How do I do this???
Please send a CC to my address (p.lemmens at nici.kun.nl), as I'm not yet 
subscribed to the list.

thank you for your help!
Paul
