Hi, I am faced with a strange problem. My picture file is empty when the following statements were run from R script. But the picture file shows up correctly, when the commands are individually run from Rgui. png(file="histogram_correlation.png", bg = "white") require(stats) histogram( ~ height | voice.part, data = singer, nint = 17, endpoints = c(59.5, 76.5), layout = c(2,4), aspect = 1, xlab = "Height (inches)") dev.off() Thanks Daren [[alternative HTML version deleted]]
