I am attempting to plot frequency of occurrence against (calendar) time. As the output is to be produced as a Powerpoint picture on a dark background I wish to make the plot output yellow > par(col="yellow", col.axis="yellow", col.lab="yellow", col.main="yellow") > plot(t2, t1, ylim=c(0,40), main="Episynlestes run 2", ylab="frequency", type="h", axes=FALSE, lwd=2) where t2 is a vector of POSIX type and t1 is the associated frequency. This works *except* that the x axis is printed ... and in black > axis.POSIXct(1, t2, col="yellow") makes the x axis yellow by overwriting, so I can get what I want (fortunately I didn't post this earlier when I was tied in a knot), but it doesn't seem elegant. Any hints?

color of plot axes involving POSIX types

plot.POSIXct doesn't have an `axes=FALSE' argument, but you can use xaxt="n". However, with your settings and my example I get a yellow axis, so I can't reproduce this.
