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")
