# [R] How to make our data normally distributed in R

```Hello,

Why would it be awkward to show values like 4600? If those are the
values, show them. When there is a large difference, orders of
magnitude, you can plot logs by setting parameter log = "y" as in

boxplot(10^(0:5), log = "y")

But I don't see why to have values in the range 2900-4600 (same order of
magnitude) is a reason to alter ylim.

Hope this helps,
