converting an R vector to a list

[ablondin]

Dear Sage community,
I'm trying to use the R interface (which means I have to learn R as
well) and it's not going too bad, but I have no idea how I can
transform an R object (a vector) to get the associated list. For
instance, if I type
sage: x = r.c([1,2,3])
sage: x
[1] 1 2 3
sage: list(x)
[[1] 1, [1] 2, [1] 3]

I would like the output not to be a list with R objects as its
elements, but simply a list. Is that possible ?

Thanks !

Alex

I answered myself.
It suffices to call sageobj on it.

sage: x = r.c([1,2,3])
sage: x
[1] 1 2 3
sage: list(x)
[[1] 1, [1] 2, [1] 3]

sage:
sage:
sage:
sage: sageobj(x)
[1, 2, 3]
sage: type(sageobj(x))
<type 'list'>

Thanks anyway !

x.sage() works great too!

I am using the fuction r.scan() because i need to read big data file,since read_table() or read_csv() is not recommended for those kind of data, witch function would be the best one, sageobj() or x.sage(), or would both do the job well, thanks in advance for you answer
