Hello,
I am trying to use the multiple imputation method to replace NAs in the
columns denoting net recalled salary (variable q32) from the file
downloadable here:

It is a survey with 17497 observations of 1681 variables, so I am reducing
I have a dataframe that I am attempting to analyze using the lmList() function
in package lme4. I'm using this funciton to select which parameters in this
model wqarrant random effects. I have a subset of the data below. I input data
and change class of necessary items so that I have several

ch.list - lmList(h12~spp+t+w+l+inih|id, data=mydata)

Hi,
The example dataset only shows 1 level for ID.

Hi,
I have been running the same code without problem for the last few days,
changing data sets etc with no issue.
Today I changed the covariates for the model and am now getting this error
message:
Error in `contrasts-`(`*tmp*`, value = contr.funs[1 + isOF[nn]]) :
contrasts can be applied
