I would like a scatterplot matrix and a correlation matrix for the
following set-up.
The data (dataframe d) are like this:

angle  resp
-90      182
-60      137
-30      ...etc
0
30
60
90
...etc

I would like each cell in the matrix to be the scatterplot of the
responses for each pair of angles ( -90 vs -60, -90 vs -30, etc). Same
for the correlation matrix.

Please tell me what to do. Thanks very much!

1) You need to "provide commented, minimal, self-contained, reproducible
  code."

d<-read.table("rstuff/data.dat",header=TRUE)

Now what? :-)

certainly it's not
pairs(d)

2) You need to fill in some missing info: Either you have only one
  response for each angle, or you need a third variable to pair up the
  corresponding responses for one angle with those of another.

contents of rstuff/data.dat:

 angle  resp  ID
 -90      182  1
 -60      137  1
 -30      123  1
 0    67  1
 30   32  1
 60   12  1
 90    13  1
-90      178  2
 -60      111  2
 -30      137  2
 0    94  2
 30   59  2
 60   1  2
 90    19  2

I actually have a lot more than 2 experimental units (ID)...

Thanks for any help
