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 ? jholtman wrote: > > Can you provide a reproducible example with the data so that we > understand what you are working with.
