Sorry Nick, I know...this question might look basic but it is quite confusing indeed. I could not find any explicit example in the help display.
In you example below, what does R[1,1] declare? Is it the name of a matrix previously defined or just stands from return.
Many thanks for your help
Ioannis

Your reply was sent in HTML. See
for how your email will appear to the majority of the members of this
list The FAQ explains that you should not send formatted posts.
As before, why not read the help to find out what you need? -help
display- makes it quite explicit that you can use -display- to display
two or more things.
For example, if a statistic were held in the first column and a
P-value in the third column of a matrix R then something like
. di %9.3f R[1,1] " " %05.3f R[1,3]
0.065 0.978
shows some possibilities. In general, you will need to specify (a)
literal text (b) numeric results (c) display formats for a decent
display. (The numbers here have no bearing on your example,
naturally.)
