Hi,
it would help if you provided a minimal example.
Here is one approach I often use with the plotting package ggplot2,
parameters <- expand.grid(m=c(0, 1), s=seq(0.1, 1,length=10))
x <- seq(-5, 5, length=300)
foo <- function(m, s){
data.frame(x=x, y=dnorm(x, m, s), m=factor(m), s=factor(s))
}
# construct a data.frame with all the data
results <- do.call(rbind, mapply(foo, m=parameters$m, s=parameters$s,
SIMPLIFY=F))
library(ggplot2)
p1 <- qplot(x, y, data=results, geom="line", colour=s, linetype=m)
p2 <- p1 + facet_grid(m~.)
results2 <- within(results, f <- factor(paste("m=", m,"; s=", s)))
p3 <- qplot(x, y, data=results2, geom="line", colour=f)
p1 # note how the legend is constructed for you
p2 # clearest imho
p3 # with 20 levels it's not very readable
Hope this helps,
baptiste

I am running a simulation many times changing one parameter each
time and recording the outcome.
I have to produce a plot to make a sense of the bunch of numbers I
get from every run.
My problem is to insert a multi-line text to keep track of which
result correspond to which parameter values.
A legend does not work in this case because I will plot 2 variables
and the corresponding experimental values.
So two curves on the same drawing as a result of the combination of
20 parameters.
I may decide to place two plots on the same canvas but if so I will
have to find the space for two 20-line texts ....
In short, I wonder how I can insert a 20-line text on each plot. I
browsed through the documentation of the par command
but I could not find any helpful option.
Thank you in advance for any suggestion.
