Would it really be so hard to
provide commented, minimal, self-contained, _reproducible_ code
?

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
plot. How do I force the boxplot to use the scatterplot's scale or something
to that effect?
My code. I'm not sure how to include the file I'm using as a dataframe:
#imports data
emdata<-read.table(file="#a file in my working directory", sep=",",
header=T)
#specifies a dataframe
foram<-data.frame(emdata)
#calculates actual dimensions in mm
foram$actual_l<-foram$length/foram$magnification
foram$actual_w<-foram$width/foram$magnification
foram$actual_h<-foram$height/foram$magnification
#takes logs of all dimensions
foram$logl<-log10(foram$actual_l)
foram$logw<-log10(foram$actual_w)
foram$logh<-log10(foram$actual_h)
#Generates scatterplot
plot(foram$stage,
foram$logl,
ylab="log max size",
xlab="stage",
cex=.1,
xaxt="n",
axes=FALSE
)
axis(at=-3:1, side=2, pos=0)
axis(at=9:84, side=1, pos=-3)
#adds a boxplot
boxplot(foram$logl~foram$stage, data=foram,
outline=F, axes=FALSE, add=TRUE, col="gray82", medlwd=1)
