In section 2.4 of the manual, it says that I should get a choice among
all covariates and interactions in looking at density estimates. I
don't see that.

That is, there is not choice for looking at re74xre74 and the like.
Not sure if this is a bug in the software or the documentation.

Is anyone out there able to use the latest version of MatchIt (which I think is
0.1-4) with the latest version of R (1.9.1) on LINUX? Will this be
possible anytime in the near future?
Any pointers would be appreciated.
Thanks,
Dave Kane
