Hi everyone,
I've been bashing my head against this for days now, and can't figure out
what to do.
I have the following dataframe
headerappetitive stimulusaversive stimuluschaining
contingencydiscriminative stimulusextinctionintermittent
reinforcementnegative reinforce
Emilio-
One possible way to do this is to create a new factor and put the levels
in the order you want them in.
For example:
related.differences$header2 <- factor(related.differences$header,
levels=c("spontaneous recovery", "negative reinforcer", ... etc. )
where you want spontaneous recovery
