If you want to use foreach to do the looping, you can use the "isplit"
function to create an iterator returning blocks of data, each block
being the data for one site:
> require(foreach)
> site.data <- read.table("isplit-data.txt",header=T) # data copied from email
> sites <- isplit(site.data,site
Try this:
foo <- function(x, dir = getwd(), ...){
png(file.path(dir, sprintf("%s.png", x)))
plot(DF.split[[x]], ...)
dev.off()
}
DF.split <- split(DF[, c("year", "peak")], DF$site)
sapply(DF.split, foo)

Hello,
I am attempting to create several plots based on "site" (~300 total)
and am having trouble with the code. I simply want to create a plot
using the code, plot(year, peak), for the following dataset. I would
like for each site to be plotted on a separate page and the plots
saved in a
