Hi,
I have just installed R 2.4.0 and when I try to load SpareseM, I get the
following error message
library(SparseM)
Package SparseM (0.71) loaded. To cite, see citation("SparseM")
Error in loadNamespace(package, c(which.lib.loc, lib.loc), keep.source =
keep.source) :
in 'SparseM' methods specified for export, but none defined:
as.matrix.csr, as.matrix.csc, as.matrix.ssr, as.matrix.ssc, as.matrix.coo,
as.matrix, t, coerce, dim, diff, diag, diag<-, det, norm, chol, backsolve,
solve, model.matrix, model.response, %*%, %x%, image
Error: package/namespace load failed for 'SparseM'
I have contacted the package maintainers and they couldn't be of any help.
I do not recall getting this error in older R versions.
Regards
Coomaren

I have been getting a similar error when I compile my own package. The message says the problem is in the "methods" package which is part of R. * checking S3 generic/method consistency ...

All contributed packages using new-style classes need to be re-installed because the internal representation of such classes and methods has changed, see CHANGES TO S4 METHODS in NEWS. Doing: update.packages(checkBuilt = TRUE) will check your libraries for packages built under previous releases and replace them with ones built for the platform release.> > I have contacted the package maintainers and they couldn't be of any help. > > I do not recall getting this error in older R versions. > > Regards > > Coomaren > > Send instant messages to your online friends http://uk.messenger.yahoo.com > [[alternative HTML version deleted]] > > ______________________________________________ > R-help at stat.math.ethz.ch mailing list > 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. >-- Roger Bivand Economic Geography Section, Department of Economics, Norwegian School of Economics and Business Administration, Helleveien 30, N-5045 Bergen, Norway. voice: +47 55 95 93 55; fax +47 55 95 95 43 e-mail: Roger.Bivand at nhh.no
