I just resorted and took the top 30 and then reordered again in the geom_bar function – below ggplot(data=st.cnt)+ geom_bar(aes(x=reorder(CourseName, -n), y=n),fill = "dark blue", stat="identity")+ theme(axis.text.x = element_text(angle = 60, hjust = 1)) Jeff From: Bert Gunter <bgunter.4...@gmail.com> Sent: Sunday, October 14, 2018 10:51 PM To: reichm...@sbcglobal.net Cc: R-help <r-help@r-project.org> Subject: Re: [R] limit bar graph output If I understand correctly, just subset your sorted data. e.g. : x <- runif(50) ## 50 unsorted values sort(x, dec = TRUE)[1:10] ## the 10 biggest -- Bert Bert Gunter "The trouble with having an open mind is that people keep coming along and sticking things into it." -- Opus (aka Berkeley Breathed in his "Bloom County" comic strip ) On Sun, Oct 14, 2018 at 7:13 PM Jeff Reichman <reichm...@sbcglobal.net <mailto:reichm...@sbcglobal.net> > wrote: R-Help Forum I'm using the following code to reorder (from highest to lowest) my miRNA counts.
