Hiii, I have some problems to plot "standard deviation and variance" from a texfile.
Ich have the following code so far: x <-read.table(file="new.txt") x$gruppe <- 100*rep(1:36, each=20) png(filename = "D:/Uni/new.png", width = 640, height = 480,pointsize = 12, bg = "white") boxplot(V3 ~ gruppe, data = x, col = "blue",boxwex=0.7,ylab ="Datenrate(MBit(sec))",xlab = "Zeit(sec)") dev.off() My question is, how can I plot the standard deviation and variance of "x$gruppe <- 100*rep(1:36, each=20)" Can anybody help me please ? greetings, johnh -- View this message in context: http://www.nabble.com/calculating-standard-deviation-and-variance-tp22306851p22306851.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
