[R] Unexpected behavior in boxplot

[Austin, Matt]

Apologies for the html mail, my company just upgraded and I forgot to change
the default mail behavior.

Version information that I also forgot:

Subject: [R] Unexpected behavior in boxplot

When plotting using the cex.axis argument to boxplot(), the size of the
plotting symbols beyond the whiskers of the boxplot are being changes.

 

Example:

 

par(mfrow=c(2,1))

boxplot(c(rnorm(10), 10), horizontal=TRUE, main="Test", las=2, cex.axis=2)

boxplot(c(rnorm(10), 10), horizontal=TRUE, main="Test", las=2, cex.axis=1)  

 

This is from the following line in bxp()

 

outcex <- pcycle(pars$outcex, pars$cex, par("cex"))

 

Where pars$cex is matching pars$cex.axis.  This would also effect other
parameter specifications.

 

This is a behavior I did not expect; I'm not sure if this is a design
feature or something else.
