matrix weirdness
I am using R on unix version 63.0
I am doing an image plot of the following data file:

image weirdness
I am using R 63.0.
Now let's try this simple image plot.
Here is the data file:
============================
lag1 lag2 cif2d
1 1 11
1 2 12
1 3 13
2 1 21
2 2 22
2 3 23
3 1 31
3 2 32
3 3 33
====================
data<-read.table("~/r/rt/data/unif/junk.out",header=TRUE)
x<-unique(data$lag1)
y<-unique(data$lag2)
z<-matrix(data$cif2d,length(y),length(x))
At this point, see the z matrix:

R-beta: image saved ps file
I include the argument
pty="s"
to image, but still when I make an image by the method
> postscript("rstuff/test.ps")
> tauseq<-seq(0,1,.5)
> cif2d.image(x,,y,tauseq)
> dev.off()
the image plot created is NOT square. I thought pty="s" would make it
square.
Generally it would be nice if the image saved to disk were like the one we
see while in R (X-windows). Are they any tips on how to make it act like
that?
Also it was mention...

x,y vs row,column
I think my problems are coused by a fundamental R incompatibility in how
matrices are stored and the usual way of specifying Cartesian coordinates.
When I do
data<-read.table("~/r/rt/data/unif/6cbcif2d.out",header=TRUE)
x<-unique(data$lag1)
y<-unique(data$lag2)
z<-matrix(data$cif2d,length(y),length(x))
This z matrix is printed apparently correctly from a Cartesian point of
view
> z
[,1] [,2] [,3]
[1,] 11 21 31
[2,] 12 22 32
[3,] 13 23 33
