It should be character for everything. My fear with factor is that it’s
converting “2”, “3”, “1” to 1, 2, 3 if those are the numbers for the factor
labels. In general, I find avoiding factors makes life much easier (with
exception of some of the plotting in ggplot2).
A good way to check format
Hi, Jovana.
Geiger’s parameters aren’t quite what you described.
SE=NA: estimate what measurement error is, not assume it’s zero. This is then a
free parameter, penalized appropriately in the AIC calculations.
SE=0 (or run geiger with defaults): force the assumption that measurement error
is z
