Hello All,
I am trying to open all files within a folder and create multiple histograms
from each file, *and* have it save with the original file name plus some new
information. The way I have it set up right now, I keep saving over each new
graph. I can turn the history on and see them all, but I want them all to
save as unique files as well. Idealy they would be "filename CHN 1mm Length
Frequency", "filename CHN 2mm Length Frequency"...and so forth. Any hints?
Thanks for your time.
Here is what I'm using now:

filenames<-dir("C:/Documents and Settings/tfish/Desktop/R/Untilted Data")
for(i in filenames){data<- read.csv(i, header = TRUE, skip = 13, sep = ",")
hist(data$X.mm.[data$SPP=="RBT"],breaks=seq(20,350,1),col="blue",main="RBT
1mm Length Frequency",freq=TRUE,xlab="Fork Length (mm)")
savePlot(filename = "RBT 1mm Length Frequency",type = c("jpg"))
hist(data$X.mm.[data$SPP=="RBT"],breaks=seq(20,350,2),col="blue",main="RBT
2mm Length Frequency",freq=TRUE,xlab="Fork Length (mm)")
savePlot(filename = "RBT 2mm Length Frequency",type = c("jpg"))
Thanks again for any and all help!
