convert incidence matrix to list
im2list_dep(x, verbose = FALSE, ...)list of character vectors, where list names
are defined by colnames(x), and vectors contain values
from rownames(x).
This function converts an incidence matrix, or equivalent
data.frame, to a list. The matrix should contain either
numeric values such as c(0, 1), or logical values such
as c(TRUE,FALSE), otherwise values are considered either
zero == FALSE, or non-zero == TRUE.
The resulting list will be named by colnames(x) of the input,
and will contain members named by rownames(x) which are
either non-zero, or contain TRUE.
Values of NA are converted to zero 0 and therefore ignored.
This function uses the transactions class from the arules
R package, which in our testing is substantially faster than
similar techniques from a variety of other R packages.
