The rnumpy concept looks great, and addresses some annoyances I've encountered working at the interface between R and numpy. I hope to test rnumpy this week, but in the meantime ... the text suggests that R data frames can be manipulated/sliced using rnumpy. Can they be created directly as well? Is that what is meant by "numpy arrays are mapped correctly by default"? If so, what's the syntax? My particular use case is conversion of flexible-type numpy arrays or numpy arrays of type object. Also, can one return a data frame that has been manipulated in R to a numpy (flexible-type) array?
Great work ... I'll get you feedback as soon as I can squeeze out some time. -best Gary On Mon, 23 Mar 2009, Nathaniel Smith wrote: > I finally had a chance to write up some quick documentation, so I > pushed out a copy of my enhanced Python->R API for feedback. > > This is an alternative to the rpy2.robjects API (it still depends on > rpy2.rinterface version 2.0.3, plus it needs numpy to be installed), > and is subject to change.
