[R] Error with R CMD check - Packages required but not available:

[Reena Bansal]

I tried to bypass R CMD check myPackage2 and did the following

R CMD build myPackage2 
R CMD INSTALL -l ~/Rlibs myPackage2 

and this works, I can load myPackage2 into my R session. Wondering why R
CMD check failed and is it not necessary for R CMD check to work before
I can build the package?

Have you *installed* myPackage1 before trying to check myPackage2?

This sort of structure certainly works for me (VarianceGamma and
SkewHyperbolic depend on HyperbolicDist).
