print median and sd...
Ok, sorry... here is my code so far... x <-read.table(file="D:/output.txt") x$grup <- 25*rep(1:144, each=5) median<-with(x, tapply(V3, grup, median)) sd<-with(x, tapply(V3, grup, sd)) I will plot to types of graph. One graph with the median values for example with the "plot()" function, the other one is the standard derivation. I will plot the s.d. with "barplot()". What do you think, is it generally common to plot the s.d. with his histograms ?

Can you provide a reproducible example with the data so that we understand what you are working with. Need to see what the structure of 'x' and 'median' are. On Fri, Mar 13, 2009 at 8:35 AM, johnhj <jharris at web.de> wrote:
Hii Jholtman, I will make a graph of the median values and not to print to the console. I tried to plot with: plot(V3 ~ grup, data = median) ?? but I get an error message. I also tried to print the output of median<-with(x, tapply(V3, grup, median)) to a text file with the X and Y Koordinates to plot it explicit with plot(x,y) but I could not figure out the X ?Values. I have not su much experience with R, I would be thankful if you could help me... jholtman wrote:
Where do you want to print it? Is it the console (if so, try 'print(median)') or if it is the plot, use 'text' with the appropriate parameters. ?It would help if you listed the " I tried many things but without success..." and what you were expecting vs. what you got. Reproducible code would be useful (and required). On Thu, Mar 12, 2009 at 10:42 PM, johnhj <jharris at web.de> wrote:
Hii, Can anybody help me, I don't know how to print the "median". Below is my code snipplet... x <-read.table(file="D:/Uni/Diplom/Diplom/Grafiken/R/BATMAN/Kabel/Batman1hop/Standardabweichung__output_30_1_Kabel(30m)_b.txt") png(filename = "D:/Grafiken/R/Standardabweichung/Kopie.png", width = 640, height = 480,pointsize = 12, bg = "white", ?res = NA) median<-with(x, tapply(V3, grup, median)) ??? dev.off() I will print, the median values with a simple line.. I tried many things but without success... I would be very appreciate, if anyone could help me... greetings, John -- View this message in context: http://www.nabble.com/print-median-and-sd...-tp22489185p22489185.html Sent from the R help mailing list archive at Nabble.com.
