package:Matrix handling of data with identical indices
In the Matrix package v. 0.995-11 I see that the dgTMatrix
Class for compressed, sparse, triplet-form matrices handles
Identically indexed data instances by summing their values,
e.g.,
library(Matrix)
(Mt <- new("dgTMatrix",
i = as.integer(c(0,0,1,1,4)),
j = as.integer(c(0,1,2,2,4)),
x = as.double(1:5),
Dim = as.integer(c(5,5))))
## 5 x 5 sparse Matrix of class
