Hi everyone,
I got the following error when I tried to diagram a confirmatory factor
analysis using lavaan:
lavaan.diagram(conf)
Error in strwidth(xvars) : plot.new has not been called yet
Does anyone have any idea about what is happening?
Thank you in advance.
Two problems with this request:
1. It would be customary to mention that lavaan.diagram
is in the psych package.
2. Is 'conf' of the appropriate class? Have you checked
with str(conf)?
