Hello Thanks for reply I want to compute several histograms in a for loop.I am trying to set the binsize constant in the beginning.
#compute the histograms for (i in 1:12) { binsize <- -20 :20/2 hist(singlefile$GVC(singlefile$new_id[,i], freq = FALSE,xlab ="Graph i", col = "pink",main ="Example Histogram", ylim = c(-3.0,3.0))) singlefile$GVCmin <- min(singlefile$GVC[1]) singlefile$GVCmin <- min(singlefile$GVC[1]) x1 <- seq(-3.0,3.0,by=.01) lines(x1,dnorm(x1),col ="black") } I tried also this but it does not do anything. I also tried your proposal , but it says that : breaks = binsize is not allowed. I think I am totaly far away from that what I want to do with my code . One single histogram plotting and computing is easy , but if it is in the loop , by the syntax to feed the function with counter i is not working Thanks Dizem -- View this message in context: http://r.789695.n4.nabble.com/hist-function-in-a-for-loop-tp4669797p4669816.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.
