MatrixToBin {GraphAlignment} | R Documentation |
Convert a matrix of real numbers to a vector of integer bin numbers according to the specified lookup vector.
MatrixToBin(M, lookup, clamp=TRUE)
M |
input matrix |
lookup |
lookup vector |
clamp |
clamp values to lookup range |
This function transforms a matrix of arbitrary values into a matrix of bin numbers corresponding to the data in the input matrix. Bin numbers are found using the specified lookup table (see GetBinNumber).
The return value is a matrix containing the bin numbers for the elements of the input matrix.
