[R] Axes Ticks

Apologies, basic question on plot.

	y <- c(-4,3,-2,1);
	x <- c("time 1", "time 2", "time 3", "time 4");
	plot(x,y, type="b");

of course fails.
	x <- 1:4
makes it succeed, but then I have too many ticks on my X axis.  I want 
exactly 4 tickmarks.  It would also be nicer if I could name the ticks.

I looked at ?par and Venables&Ripley, and tried the lab and xaxp 
parameters.  I could not figure out how to use them productively.  could 
someone please let me know?  help appreciated.  /iaw
