datadist() in Design library

[array chip]

Hi I got an error message using datadist() from Design package:

> library(Design,T)
> dd <- datadist(beta.final)          
> options(datadist="dd")
> lrm(Disease ~ gsct+apcct+rarct, x=TRUE, y=TRUE)
Error in eval(expr, envir, enclos) : object "Disease" not found

All variables inclduing response variable "Disease" are in the data frame "beta.final", why then "Disease" can not be found? I thought with datadist(), all variables are presented to the model fitting functions. maybe I am wrong?

thanks

John

Dear John,
Have you tried it specifying the 'data' argument as suggested in lrm help?

Try this:

 lrm(Disease ~ gsct + apcct + rarct,  data = beta.final, x = TRUE,  y = TRUE
)

HTH,

Jorge

Dear Jorge, Yes, with "data=beta.final" in the lrm(), it worked. But I thought one of the reasons for datadist() is to make it unnecessary to specify the data frame in the lrm(). Maybe I am completely wrong here.

Thanks

John
