R help - Feb 2010 - Error with R CMD check - Packages required but not available:

Hi All,

Apologies in advance if this is not the right email to post this
question.

I successfully created my first R package myPackage1.
Now I want to create another R package myPackage2 which requires
functions from myPackage1.

However when I try R CMD check myPackage2 I get the following error

* checking for working pdflatex ... OK
* using log directory '.../myPackage/myPackage2.Rcheck'
* using R version 2.9.2 (2009-08-24)
* using session charset: UTF-8
* checking for file 'myPackage2/DESCRIPTION' ... OK
* checking extension type ... Package
* this is package 'myPackage2' version '1.0'
* checking package dependencies ... ERROR
Packages required but not available:
  myPackage1

See the information on DESCRIPTION files in the chapter 'Creating R
packages' of the 'Writing R Extensions' manual.

My DESCRIPTION file looks like this

Package: myPackage2
Type: Package
Title: myPackage2
Version: 1.0
Date: 2010-02-02
Author: RB
Maintainer: <rb@xyz.com>
Description: myPackage2
Depends: myPackage1
License: What license is it under?
LazyLoad: yes


I have also checked .libPaths() and it has the right path to find
myPackage1 in my local R library. Any suggestions?

Thanks,
Reena

Have you set the environment variable R_LIBS to include the library 
which myPackage1 has been installed into previously?

Best,

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).
