Hello, everyody, when asking, e.g., Effect() to compute the effects of a fitted, e.g., linear model after having deleted the data frame from the workspace for which the model was obtained an error is reported:
> myair <- airquality > fm <- lm(Ozone ~ Temp, data = myair) > rm(myair) > Effect("Temp", fm) Error in eval(model$call$data, envir) : object 'myair' not found Has anybody a better "workaround" for this than, e.g., explicitly saving the fitted model object fm together with its original environment or just the data needed frame (maybe in a list like fm.plus.origdata <- list(fm, myair = myair)) to be able to restore the original environemt (or at least the needed opriginal data frame) of the time when fm was created? Thx for any hint!
