How to create horizontal lines for each bar in a bar plot of base R?
To create horizontal lines for each bar in a bar plot of base R, we can use abline function and pass the same values as in the original barplot with h argument that represents horizontal with different color to make the plot a little better in terms of visualization.
Example
x<-c(24,25,22) barplot(x) abline(h=c(24,25,22),col="red")
Output
Example2
y<-rpois(5,2) y
Output
[1] 4 0 2 2 4
Example
barplot(y) abline(h=c(4,0,2,2,4),col="blue")
Output
