Does the prtest argument help when you actually use the 'print' function around your summary.formula object? I think that's how I solve it.
I.e., sf1 <- summary(trt~sex+ascites,data=ex,test=T,method="reverse",catTest=u) print(sf1, prtest = "P") Descriptive Statistics by trt +-------+---+---------+---------+-------+ | |N |1 |2 |P-value| | | |(N=158) |(N=154) | | +-------+---+---------+---------+-------+ |sex : f|418|87% (137)|90% (139)| 0.377| +-------+---+---------+---------+-------+ |ascites|312| 9% ( 14)| 6% ( 10)| 0.526| +-------+---+---------+---------+-------+ ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
