Hi, I have written a script that currently reads in a .txt file where I specify the name e.g mydata<-read.table("a_date.txt", header=TRUE) The script eventually produces a plot, e.g: pdf(file="myfilename.txt") plot(etc) dev.off What I want to do is run this script on several input files in my directory, without having to manually change the input file name each time, and produce the output plot pdf with the input file name as the output file name. It would also be handy if my plot title is also the input file name. I'm relatively new to R so i'm not sure how to approach this. I presume it's some sort of loop function, but i've never implemented one of these before - any advice would be greatly appreciated! Thanks in advance!
