multiple barplots in R side by side

Question

I have two vectors like this:

multistakeuserutil<-c(24.0, 71.0, 75.0, 109.0, 134.0, 126.0, 117.0, 446.0, 283.0, 162.0, 109.0)
reguserUtil<-c(10.0, 50.0, 38.0, 67.0, 73.0, 72.0, 69.0, 263.0, 146.0,   87.0, 70.0)

Now, I plot multistakeuserutil using this line of code:

barplot(multistakeuserutil,col="darkgreen")

And then I plot reguserUtil like this:

barplot(reguserUtil,col="red")

which gives me a separate plot. But I want this two bar chart to be in one picture and side by side for easier comparison. Any idea how I can do that?

Answer 1

This might be useful for you.

test <- cbind(multistakeuserutil,reguserUtil)

barplot(test,beside=T)

If you want to do better comparison, then this is best according to me.

test2 <- rbind(multistakeuserutil,reguserUtil)

barplot(test2,beside=T)

Answer 2

Use mfrow():

par(mfrow = c(1:2))

barplot(multistakeuserutil,col="darkgreen") 
barplot(reguserUtil,col="red")
