frame <- read.table(paste('data', fname, sep="/"), sep=",", header=true) colnames(frame) <- c("pos", "word.length") plot <- ggplot(frame, aes(x=pos, y=word.length)) + xlim(0,20) + ylim(0,20) + geom_density2d() + stat_density2d(aes(color=..level..)) png(paste("graphs/", fname, ".png", sep=""), width=600, height=600) print(plot) dev.off()
