[R] limit bar graph output

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))

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

I'm using the following code to reorder (from highest to lowest) my miRNA
counts.  But there are 500 plus and I only need the first (say) 15-20.  How
do I limit ggplot to only the first 20 miRNA counts

ggplot(data = corr.m, aes(x = reorder(miRNA, -value), y = value, fill =
variable)) + 
  geom_bar(stat = "identity")
