Answering my own question. I managed to get scripts to work both with
R and with XYPic. Very little hacking is needed, though I'm probably
breaking lots of stuff.

I edited the files
/usr/share/TeXmacs/plugins/xypic/progs/init-xypic.scm
and
/usr/share/TeXmacs/plugins/xypic/progs/init-r.scm

To both I added a line to plugin-configure:

(plugin-configure xypic
(:require (url-exists-in-path? "latex"))
(:launch "tm_xypic --texmacs")
(:session "XYpic")
(:scripts "XYpic"))

and
(plugin-configure r
(:require (url-exists-in-path? "R"))
(:initialize (r-initialize))
(:serializer ,r-serialize)
(:launch "exec tm_r")
;; (:tab-completion #t)
(:session "R")
(:scripts "R")
)

(The added line is the last - (:scripts "name"))

Once that is done, in a document, you just select
Document->scripts->XYPic (or R), and then hit M-*!
Then you enter an expression, and when you want to evaluate it hit C-*
To unevaluate it, i.e. see the original expression, hit C-* again.

Thus, for R you can enter the expression
plot(1:10,10:1);abline(0,1,col=2);v()
and then you get a nice graph in the document....

If you want both R and XYPic in the same session, it seems you have to
select Document->scripts->XYPic before you enter the expression with
M-*!, you can not just edit the grey field that says R or XYPic.

It is a bit hard to differentiate parts of the text that are output of
scripts from parts that are just text (I guess that is the point...).
Is there something like varsession for scripts?
