Loading required namespace: MatrixModels
When sourcing ?rq.R?:
Error: could not find function "sparse.model.matrix"
Execution halted
This is baffling to me since sparse.model.matrix is in the
namespace of Matrix and it should be loaded at this stage
since it is required by MatrixModels which has just been
pronounced "loaded".
I've verified that I can Sweave("rq.Rnw")
and texi2pdf("rq.tex", clean=TRUE) without any problem.
Any hints greatly appreciated, as always.
This could happen if you load the namespace of MatrixModels (e.g. by using :: notation), but don't put it on your search path (e.g. by using library(MatrixModels)). When you run Sweave from within R, it sees the search path that was active when you called Sweave; when checking a vignette, it starts with a clean slate. Duncan Murdoch
