Dear participants and subscribers of the R-help mailing list,
I would like to compare two dependent correlations with one overlapping
variable. The Meng Z1 method seemed suitable for this purpose. I found out that
the "cocor" package is required for this instrument. I checked several times
whether the package was installed and activated and both were the case. I have
also tried the "psych" package, but I get the same error in both cases:
> library(cocor)
> library(psych)
> test2r.mengz1(corAVOBMI, corAVVBMI, corAVOAVV, 39)
Error in test2r.mengz1(corAVOBMI, corAVVBMI, corAVOAVV, 39) :
could not find function "test2r.mengz1" (Translated from German)
Do I not have the right package? Or can you recognize another error?
Many thanks in advance.
Yours faithfully
Justine Alligand
