%description
PAM (Partitioning Around Medoids) algorithm application to samples of
single cell sequencing techniques with a high number of cells (as many as
the computer memory allows). The package uses a binary format to store
matrices (either full, sparse or symmetric) in files written in the disk
that can contain any data type (not just double) which allows its
manipulation when memory is sufficient to load them as int or float, but
not as double. The PAM implementation is done in parallel, using
several/all the cores of the machine, if it has them. This package shares
a great part of its code with packages 'jmatrix' and 'parallelpam' but
their functionality is included here so there is no need to install them.
