hello all,
I am trying to use the function getCovariateFormula(nlme) in conjunction with
the library lme4. When I load both packages I get the following message and the
getCovariateFormula function no longer works:
library(nlme)
library(lme4)
Attaching package 'lme4':
The following object(s) are masked from package:nlme :
contr.SAS getCovariateFormula getResponseFormula groupedData lmeControl
I have tried removing the package after using it, with:
detach(package:lme4)
library(nlme)
but I still get an error message when I try to use getCovariateFormula. The line
I use it in, and the error message is below:
rownames(table)<-c((getCovariateFormula(model1)),(getCovariateFormula(model2)),(getCovariateFormula(model3)),(getCovariateFormula(model4)),(getCovariateFormula(model5)),(getCovariateFormula(model6)),(getCovariateFormula(modelnull)))
Error in switch(mode(x), "NULL" = structure(NULL, class =
"formula"), :
invalid formula
This line works fine when I run models with different structures that are not in
the lme4 package.
Does anyone have any suggestions about this ?
Am I not removing the package completely ?
Any suggestions would be greatly appreciated
Thanks
James Smith

To attach lme4 you must restart R without package nlme. Error: .onLoad failed in loadNamespace for 'lme4' Error in library(lme4) : package/namespace load failed for 'lme4' So the answer is: Don't do that.
