[R] Histogram plot help
Dear All: I plotted a histogram with Abline, clipping with color codes but i run into some problems. The abline' does not show up at all, and when i request the 'prob=True' (to obtain the freqs), my clipped region colors the section of the graph instead of the plot only. Is there any way i can get the y-axis figures to be in whole numbers rather than decimals? Many thanks for your help. YA Here are the working codes i am tweaking. Everything worked fine before i trying adding stuffs (prob=T, etc). x - rnorm(1000) hist(x, xlim=c(-4,4),ylab=Prevalence,prob=T,lwd=3,las=1) lines(density(x),col=black,lwd=2) usr - par(usr) clip(usr[1], -2, usr[3], usr[4]) hist(x, col = 'red', add = TRUE) clip(2, usr[2], usr[3], usr[4]) hist(x, col = 'blue', add = TRUE) abline(v=c(-1),lty=1,lwd=3,col=black) do.call(clip, as.list(usr)) # reset to plot region -- View this message in context: http://r.789695.n4.nabble.com/Histogram-plot-help-tp4651958.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.
Re: [R] Histogram plot help
Hello, I can't say I understand your graph but as for the abline not showing up, it's outside the clipped region so it shouldn't. If you want it to show up, in the previous line, and after the hist() call, include clip(2, -2, usr[3], usr[4]) As for the decimals, those are normal, have you seen the data you're ploting? To have whole numbers use the arguments ylim and yaxt = n in the first call to hist and axis(2, ...) afterward. Something like hist(x, xlim=c(-4,4),ylab=Prevalence,prob=T,lwd=3,las=1, ylim = c(0, 3), yaxt=n) axis(2, at = 0:3) Oh, and you forgot prob = TRUE in the other calls to hist().

Re: [R] Histogram plot help
Does it work the way you want if you add prob=TRUE to the second and third hist() commands and run do.call() before abline()? -- David L Carlson Associate Professor of Anthropology Texas AM University College Station, TX 77843-4352 -Original Message- From: r-help-boun...@r-project.org [mailto:r-help-bounces@r- project.org] On Behalf Of YAddo Sent: Monday, December 03, 2012 4:22 PM To: r-help@r-project.org Subject: [R] Histogram plot help Dear All: I plotted a histogram with Abline, clipping with color codes but i run into some problems.
