Dear all,
How to install function effects in R 3.1.2.? I got this:
plot(effect("soil:volatile", model1))
Error in plot(effect("soil:volatile", model1)) :
could not find function "effect"
Error in find.package(if (is.null(package)) loadedNamespaces() else package, :
there is no package called ''
Thank you very much,
Xavier
