Boxplots over a Scatterplot
Hello-
I'm new to R, coding and stats. (Oh no.)
Anyway, I have about 12000 data points in a data.frame (dealing with
dimensions and geological stage information for fossil protists) and have
plotted them in a basic scatter plot. I also added a boxplot to overlay
these points. Each worked fine independently, but when I attempt to
superimpose them with add=true, I get a different scale for the boxplot,
which results in it being shifted back to the left relative to the scatter

Hi all,
I'm working on a multinomial (or "polytomous") logistic regression
using R and have made great progress using multinom() from the nnet
library. My response variable has three categories, and there are two
different possible predictors. I'd like to use the likelihoods of
