Hello,
How can i 'fix' the following output.
v=viewport(x=216/2, y=216/2,w=216, h=216,default.units = "bigpts")
pushViewport(v)
x=c(119,130,140,151)
y=c(124,124,124,124)
grid.points(x,y,size=unit(1,"bigpts"),default.units="bigpts",pch=".")
grid.points(x-2,y,size=unit(1,"bigpts"),default.units="bigpts",pch=".")
grid.points(x+2,y,size=unit(1,"bigpts"),default.units="bigpts",pch=".")
grid.points(x,y-2,size=unit(1,"bigpts"),default.units="bigpts",pch=".")
grid.points(x,y+2,size=unit(1,"bigpts"),default.units="bigpts",pch=".")
One would expect to get a 4 figures composed of 5 dots each - 2
vertically spaced and 2 horizontally spaced symmetrically around the
center dot.
However i seem to get odd results - e.g on Quartz(OS X) output, the
last command, places the dot bang next to the center dot.
On 'jpeg' output with higest quality, this oddity happens with the 'x
+2' command.
This doesn't happen to all of the points, only some - and not necc.
the edge figures.
Is there anyway i can control this?
Thanks
