Re: [R] installing a new package

At the risk of oversimplifying, there are three steps to developing and using a package:

  1. build
  2. install
  3. load

Evidently your package does steps 1 and 2 but not 3.

Furthermore, it tells you, "not a valid package", and says something that is suggestive of a version problem:

   "installed < 2.0.0"

I think you have to look very carefully at your package and look for what is invalid about it. There must be some requirement of package structure, or contents, or version of something, that your package doesn't meet or violates.

Since your package can be installed, go into R, and try

   require(HighProbability)
but set the verbose argument to something that gives more information than the default. Maybe that will give some helpful information, more than the check provides.

Either that, or delve deeply into the CMD check script(s) and find out exactly what can trigger the error message.

Anyway, that's the best I can come up with, without actually having the package files.
