Good Morning,
I am trying to get side by side boxplots of two groups on the
same variable. The last item under ?boxplot led me to some useful
code.
I use "boxwex" to make the boxes narrower, "at" to shift them
over and "add" to draw them both on the same graph. Something along
the lines of:
attach(group1)
boxplot(Y~X, col="blue", boxwex=.4, at=1:n+.2)
attach(group2)
boxplot(Y~X, col="red", boxwex=.4, at=1:n-.2, add=TRUE)
When I just make up a small dataset to try this out on it
works great. My problem is that I don't have completely matching
data in the real dataset. Every instance of the variable does not
have data present from both groups. When they get put on top of each
other they don't line up.
Can I do something with my data to make it line up correctly
using this approach? Is there another way of getting the same
results?
Thanks,
Phillip
