I have some data like

`A 2 A 4 A 76 B 8 B 13 .. .... `

Basically, what is the spread of A, B, etc.

What would be a suitable graph to visualize such information in R?

#### Best Answer

There are numerous possible displays, depending on what more specifically you want.

One example would be a boxplot for each group (A, B, …) (assuming there are enough values in each group to support one*):

`boxplot(len~supp,data=ToothGrowth,horizontal=TRUE,boxwex=.7) `

But you might want to look at histograms, ecdfs, or a number of other possibilities

* Edit: from your later comments, it looks like there's enough data for boxplots.
