I get what I initially thought was unexpected behaviour from: x <- tapply(runif(100), sample(5, 100, TRUE), mean) solve(Diagonal(5), x) # Error: not-yet-implemented method for solve(<ddiMatrix>, <array>). # ->> Ask the package authors to implement the missing feature.
This is because x is a 1-D array, so the operation is not well-defined. Would it make sense for Matrix to support this (treat 1-D arrays as column vectors, as it does for plain vectors)? Or should I make my intent clear with solve(Diagonal(5), as.vector(x)) ? -Deepayan ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
