Given a partition, coerce to a nice compact character format
Usage
condense(x, minval=1, col)
Arguments
x
A partition or a matrix whose columns are partitions
minval
Minimum value to include in the printing, defaulting to
1 [meaning to ignore zero values]. Set to “0” for compositions
col
String specifying the collapse value with missing value
meaning to use the empty string if values are all single digit, and
a comma if not. Using “+” is good for actual
partitions
