Dunno exactly whom I should ask about this problem, but I thought I'd start with good old r-help. I have recently acquired a new laptop, and have installed Ubuntu 16.04 on it. Still having some teething problems. If I do plot(1:10,ylab=expression(italic(J(r))) I get the error: Error in title(...) : X11 font -*-courier-%s-%s-*-*-%d-*-*-*-*-*-*-*, face 5 at size 15 could not be loaded So it would seem that I am missing a font. Fonts have always been a complete mystery to me. Can anyone suggest how I might rectify this deficiency in the fonts on my system? If so, *please* be as explicit as you can in your instructions; I am all at sea here. cheers, Rolf Turner P. S. I have also just noticed that if I do: plot(1:10,ylab=expression(alpha)) I get an "a" as the y-axis label, rather than the Greek letter alpha. Likewise if I do plot(1:10,ylab=expression(Sigma)) I get a capital "S" rather than an upper case Greek Sigma symbol. No error thrown, but. Any ideas as to how to fix this problem?

Hi Rolf, I would try using dnf (or whatever the Ubuntu equivalent is) to install the X11 fonts. You may have a GUI method for this in Ubuntu.

There is R-sig-debian (Ubuntu is a derivative of Debian), but to be honest, this seems more like a question for askubuntu.com. -- Sent from my phone. Please excuse my brevity.

Finally figured out the apt-get command analogous to the old yum command. (Different package name(s); took me a while to find/figure out what the appropriate names are. I'm *slow*!!!)
