Adjust For

Specify a list of other factors and/or covariates in the model, and specified adjustment values for these. If left blank, the adjustment values will be the average over the levels of every (non-focus) factor in the model, and the grand average values of numeric covariates. Several combinations of values may be specified for each factor/covariate; adjusted means for the focus factor will be computed for every combination of values specified in the adjust list.

Although a dropdown list displays the variables available, values must be specified using a list of name=c(value) terms. For example: Weight=c(2500, 3500).
