Cell counts and differences for a series of datasets
A (named) sequence of R objects carrying data (e.g.
A list of R objects carrying data; will be concatenated with objects in
How to compare the datasets.
An object of class
cellComparison, which is really an array
with a few attributes. It counts the total number of cells, the number of
missings, the number of altered values and changes therein as compared to
the reference defined in
This function assumes that the datasets have the same dimensions and that both rows and columns are ordered similarly.
