R help - Aug 2014 - problem with labeling plots, possibly in font defaults

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!

It hasn't happened to me recently (since updating from Leopard and
SnowLeapard to Lion)  but it used to happen pretty frequently that I would get a
duplicate font that printed empty square boxes. (I wasn't the only one. It
got reported several times on R-SIG-Mac.)  One could fix that sort of problem by
deleting the offending duplicate entry using Font Book.app

Since this is happening with the default serif font,  you would probably find
the duplicate in Times. (It used to be happening to me with Symbol.)

"Times-BoldItalic"
