I have updated the rms package to extensively use NAMESPACE. I cannot get certain S3 methods to dispatch. For example I have in NAMESPACE S3method(anova, rms) S3method(latex, anova.rms) anova.rms produces an object of class "anova.rms" and there is a latex.anova.rms function in rms. But when I do latex(anova(fit)) I get an invocation of latex.default. I have tried using "anova.rms" and `anova.rms` in S3method() to no avail. Any help appreciated. I'm using R 2.15.3 Frank ----- Frank Harrell Department of Biostatistics, Vanderbilt University -- View this message in context: http://r.789695.n4.nabble.com/Problem-with-S3-method-dispatch-and-NAMESPACE-tp4665179.html Sent from the R devel mailing list archive at Nabble.com.

[Rd] Solved and Question: Problem with S3 method dispatch and NAMESPACE
I found that package quantreg has created a new generic for latex() [I wish it hadn't; this has been a generic in Hmisc for almost 2 decades]. When I require(quantreg) after loading rms, latex(anova.rms object) dispatches latex.default, but everything is fine if I don't load quantreg. rms has import(Hmisc) in NAMESPACE and is loaded before quantreg, hence the conflict. How do I make the generic from Hmisc take precedence? Thanks Frank Frank Harrell wrote> I have updated the rms package to extensively use NAMESPACE. I cannot get > certain S3 methods to dispatch.
