Ahhh. That worked perfectly. Thank you very much.

Basically, I want 181 points equally spaced over a 40 x 40 cm area. I want
to be able to specify the number of points and the area to which they are
plotted on. I think you are right that grid is what I am looking for but I
was the grid to have axes which your code below, although appreciated, did
Still not sure exactly what you want, but it sounds like the 'grid'
package may be of some help.
It has very flexible ways partitioning regions for plotting. Is this
anything like you're after?
library(grid)
for(i in 0:10)
for(j in 0:10)
grid.points(i / 10, j / 10, default.unit = "npc
Right equidistant was clearly the wrong word. Sorry. I just meant that any
given point should have an equal distance from the four points immediately
surrounding it (x,-x,y-y) aside from those on the edge which will obviously
only have two or three points surrounding.

What do you mean by equidistant? You can have three points that are
equidistant on the plane, but there's no way to add another point and
have it be the same distance from all of the existing points. (Unless
all the points are in the same place)

This might not possible in R but I thought I would give it shot. I am have to
set up a 40 x 40 cm grid of 181 points equidistant from each other. Is there
any way to produce a graph with R that can do this for me? Actual sizes are
unimportant as long it is to scale. Thanks
