There are several ways. The closest to yours, although not the safest one(*), might be: import rpy2.robjects as ro d = dict(x = [1,2], y = [2,3]) dataf = ro.r['data.frame'](**d) (*: not the safest one because python dictionaries do not conserve the order, and because R list do not enforce unique names - using rpy2.rlike.container.TaggedList and rpy2.robjects.RDataFrame intends to be "safer") L. > > Laurent > > ------------------------------------------------------------------------- > This SF.Net email is sponsored by the Moblin Your Move Developer's challenge > Build the coolest Linux based applications with Moblin SDK & win great prizes > Grand prize is a trip for two to an Open Source event anywhere in the world > http://moblin-contest.org/redirect.php?banner_id=100&url=/ > _______________________________________________ > rpy-list mailing list > rpy-list@lists.sourceforge.net > https://lists.sourceforge.net/lists/listinfo/rpy-list ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ rpy-list mailing list rpy-list@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/rpy-list
