Examples

 x <- 1:10
 y <- 1:10
 z <- outer(x,y,function(x,y) { 3*sin(2*pi*x)/(2*pi*x)+exp(y/10)+(x*y)/1000 })
 par(mar=c(5,10,2,2))
 pp <- perspx(x,y,z,ticktype="detailed",phi=30,theta=80,nticks=3,r=10,
      axes=FALSE)
 ## axis labels not drawn when axes=FALSE
 paxis3d("X-",pp,at=c(1,2,9))
 paxis3d("Y+",pp)
 paxis3d("Z-",pp)
 mtext3d("X-",pp,expression(alpha^sqrt(beta)))
 ## if you want labels parallel to axis, still have to figure out 'srt'
 ##   by trial and error
 mtext3d("Y+",pp,expression("velocity ("*gamma*", furlongs/fortnight)"),
        xpd=NA,srt=6)
 mtext3d("Z-",pp,"Range\n(r*)",dist=0.5)
