Thanks for this package!
I'm trying to use addlvariables option, but when supplied a data.frame with
factor columns, it returns
r in x * w : non-numeric argument to binary operator
In addition: Warning messages:
1: In mean.default(x1, na.rm = T) :
argument is not numeric or logical: returning NA
2: In mean.default(x0, na.rm = T) :
argument is not numeric or logical: returning NA
This problem doesn't occur with numeric columns, and not with the main
matchit function. What am I missing?
Thank you in advance,
Oren
