installing a new package

 * checking whether the package can be loaded ... ERROR
 Error in library(HighProbability) :
  'HighProbability' is not a valid package -- installed < 2.0.0?
 Execution halted

Although it might be obvious, can you load this package manually, that
is running
library(HighProbability)
at the R prompt? And is this package a dependency of your own package?
