Re: [sage-support] Some R integration samples - is there better way to do it?
ah, thanks - I know about r.tab, well - most of it are R commands, the
issue is that I didn't found those sage specific ones - it would help
if at least list of modified commands would appear in r? docstrings.
Anyway, is r.set working? I used:
sage: r.ls()
character(0)
sage: r.set('y', r([1,2,3]))
sage: r.ls()
[1] sage0 sage1 sage2 sage3 sage4
and there is no variable 'y' in R env. (using sage 4.4.2 here, was it
fixed/added/changed later on?) - anyway, variable 'y' is inserted when
I used:
%r
letSage - function(variable,value) { .GlobalEnv[[variable]]-value }
def setR(var, val):
r.letSage('%s'%var, r(val))
and called it with:
setR('y', [1,2,3])
so it still isn't what I look for, thout the r(...) for val helped
to simplify it a lot. The r('var - val') works, but requires to
specify val as R code, so it's not best way I think. I'm looking for
something you can pass list as argument, and preferably without r code
and function above. The r.set if it worked would be nice I think :)
cheers,
Andrzej.

sage: sageobj(r('x')) # r('x').sage() works too

Oh, and:
sage: r.set('y', r([1,2,3]))
sage: r('y')
[1] 1 2 3
Try:
sage: r.TAB
for more commands.

[sage-support] Some R integration samples - is there better way to do it?
