Hello,

I am using R 3.1.1 on a (four year old) MacBook, running OSX 10.9.4.

I just tried making and labeling a plot as follows:

> x<-rnorm(10)
> y<-rnorm(10)
> plot(x,y)
> title(main="random points")

which produces a scatter plot of the random points, but without the title
and without any numbers along the axes. If I then run

> par(family="sans")
> plot(x,y,main="plot title")

the plot has the title and the numbers on the axes (also and 'x' and 'y'
appear as default labels for the axes).

I do not know what is going on, but maybe there is some problem in the
default font settings (I don't know if that could be an R issue or an issue
specific to my Mac)?

This is clearly not a big problem (at least for now) since I can put labels
on plots by running par(), but if it is indicative of a larger underlying
problem (or if there is a simple fix) I would like to know.

Thank you!
