Value incidence matrix to list
im_value2list(x, empty = c(NA, "", 0), ...)list whose names are set names derived from colnames(x),
and where each vector is named using rownames(x) and the
values from x, for non-empty values.
This function is the reciprocal to list2im_value().
A value incidence matrix is a matrix whose non-empty values are retained in each item vector, where items are stored as vector names.
This function is most commonly used with signed values
c(-1, 0, 1), to indicate direction where 1 is up,
-1 is down, and 0 is not changed. In this case 0
which is considered empty by default.
