R devel - Nov 2008 - cex.lab etc. ignored in plot.ts for multiple plots (PR#13315)

When plotting multiple time series in a single plot, via
plot.ts(plot.type="multiple"), the cex.lab, col.lab, and font.lab
arguments are
ignored
> plot(ts(data.frame(a=1:10, b=1:10)), plot.type="single",
cex.lab=0.5,
col.lab="red")  #tiny red axis labels
> plot(ts(data.frame(a=1:10, b=1:10)), plot.type="multiple",
cex.lab=0.5,
col.lab="red") #should have tiny red axis labels, but does not.

I think this a problem with lines 54-57 of plot.ts. In particular, the mtext
functions should also be called with 'cex=cex.lab, col=col.lab,
font=font.lab',
and the argument list of the plotts function should also contain
'cex.lab=par("cex.lab"), col.lab=par("col.lab"),
font.lab=par("font.lab")'

As a workaround you could use plot.zoo:

library(zoo)
tt <- ts(cbind(a = 1:10, b = 1:10))

plot(as.zoo(tt), plot.type="multiple", cex.lab = 0.5, col.lab =
"red")
