Re: [R] Simple plotting errors
I'd suggest you first combine the 12 data.frames into one, using
melt() from the reshape package.
makeDummy - function(.){ # since you don't provide a reproducible
example
data.frame(x=letters[1:10], y=rnorm(10))
}
listOf12DataFrames - lapply(1:12, makeDummy)
library(reshape)
dm - melt(listOf12DataFrames, id=x)
str(dm) # each original data.frame is identified by the integer L1
with(subset(dm, x==a),
plot(L1, value, t=l))

Re: [R] Simple plotting errors
Thanks for all the useful information; use of 'c(...)' did the trick, although in future I'll try to hold the data in a more user-friendly setup. I've now got a plot, but have two issues that I can't seem to resolve: 1, The ylab is overlapping the y-axis tick mark values. I've tried using oma and mar to adjust the outer and plot margins respectively, but this doesn't seem to 'detach' the overlapping text. 2. The x-axis currently has tick mark values of 2 to 12. How do change this to single-letter month labels? So far I've tried xlim=c(J,F,M,A,M...) and names.arg=c(J,F,M...), but these result in errors. Any suggestions would be much appreciated.
