help(par) says:
'mfcol, mfrow' ...
In a layout with exactly two rows and columns the base value of
'"cex"' is reduced by a factor of 0.83: if there are three or more
of either rows or columns, the reduction factor is 0.66.
In reality, par(mfrow =) *resets* par ('cex'), not reduces it as
documented. To reproduce:
par(cex = 0.5)
par(mfrow = c(2, 2))
print(par('cex'))
It outputs 0.83, not 0.415 as expected.
Particularly such a behavior makes plot.ts and plot.acf effectively
ignore par('cex') value for the multivariate case. I guess there are
more situations where the documented behavior would be more
appropriate.
I'm ready to provide any additional info,
Andrey
