Gabor,

I thought that I had worked around the 'expression' format problem, but if the x-y labels are to be bold, then using,say, cex.lab=1.25 in the title(), appears to simulate 'bold' font very well, both for the ylab maths expression and xlab text.

Your solution is the rigorous one!

John

for example --

plot(rnorm(10),rnorm(10),xlab=" ",ylab=" ") title(xlab="year",
ylab=expression(paste("M x"*10^{3})),font.lab=1,col.lab=4, cex.lab=1.25)

Trying characters and expressions variously it seems that font.lab applies to character strings but not to expressions so if you want to use an expression
just use bold (or whatever) explicitly on the expression. One gotcha is that
bold will not work as one might have expected on numbers so they must be represented as character strings -- which is why we have used "3" rather than 3 below.

plot(rnorm(10),rnorm(10),xlab=quote(bold(year)),ylab=quote(bold("Mx10"^"3")) )
