[R] question how to add Standard Deviation as Whiskers in a simple plot
Dear Researchers, sorry for this simple question. I have a point plot with mean values and i wish to plot line with Standard Deviation as Whiskers. I calculate the mean+sd and mean-sd, but i can not figure out the way to add the line. mydata - data.frame(mean=c(0.42,0.41,0.41,0.43,0.45,0.43,0.43,0.42,0.44,0.45,0.45,0.45,0.46,0.43,0.42,0.37,0.44,0.46,0.46,0.39,0.40), sdUP=c(0.58,0.56,0.55,0.57,0.61,0.55,0.57,0.59,0.61,0.60,0.57,0.60,0.62,0.57,0.59,0.56,0.57,0.61,0.61,0.56,0.54), sdDOWN=c(0.26,0.26,0.28,0.29,0.30,0.30,0.29,0.26,0.28,0.31,0.34,0.30,0.31,0.30,0.25,0.19,0.31,0.31,0.31,0.22,0.25)) plot(mydata$mean, type=o, ylab=mean, xlab=class) thanks in advance and sorry for any disturb Gianni [[alternative HTML version deleted]] __ 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.

Re: [R] question how to add Standard Deviation as Whiskers in a simple plot
The function i am looking is a bars from the mean points of the plot in boxplot style. I tryed several forum but I have no clear the way to create these bars.

Hello, The function 'arrows' with angle=90 can do the job. mydata - data.frame(mean=c(0.42,0.41,0.41,0.43,0.45,0.43,0.43,0.42,0.44,0.45,0.45,0.45,0.46,0.43,0.42,0.37,0.44,0.46,0.46,0.39,0.40), sdUP=c(0.58,0.56,0.55,0.57,0.61,0.55,0.57,0.59,0.61,0.60,0.57,0.60,0.62,0.57,0.59,0.56,0.57,0.61,0.61,0.56,0.54), sdDOWN=c(0.26,0.26,0.28,0.29,0.30,0.30,0.29,0.26,0.28,0.31,0.34,0.30,0.31,0.30,0.25,0.19,0.31,0.31,0.31,0.22,0.25)) x - 1:nrow(mydata) with(mydata, plot(1, type=n, xlim=c(1, nrow(mydata)), ylim=c(min(sdDOWN), max(sdUP with(mydata, points(x, mean)) with(mydata, arrows(x, mean, x, sdUP, angle=90, length=0.1)) with(mydata, arrows(x, mean, x, sdDOWN, angle=90, length=0.1)) Hope this helps, Rui Barradas Em 28-05-2012 18:24, gianni lavaredo escreveu: The function i am looking is a bars from the mean points of the plot in boxplot style.
