[R-sig-eco] question about plot

[Luis Fernando García]

Dear R friends,

I have to produce a plot like the one attached on the file. The idea is to
plot the time spent for a spider over several different prey, the spiders
were repreated in the different trials. If any of you knows how to perform
this plot or have any source which explains how to do it, I would really
appreciate it.

Thanks in advance.
