R-beta: par(tck=xxx) not working?

[U-E59264-Osman Buyukisik]

Hi,
 I was trying to get grid lines drawn in an XY plot. I set par(tck=1),
and then issued a plot command. Grid lines were not drawn. tick lines
were in their usual(default) places and lengths. I tried setting tck
in the "plot" function, but to no avail. Any help would be
appreciated. I checked to see if different values were stored, and
they were. foo<-par() shows tck to be 1.0. The source also showed that
in par.c they were stored inp GP<-tck, but not used in plot.c.
BTW I am using R-0.50-a1 on an hpukes-10.2.

TIA
Osman
