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.
