2    
3            * NAMESPACE: exported drop0(), since
4            * man/drop0.Rd: I have seen several cases, I really wanted to use
5            it, so our users may want too.
6    
7    2007-05-22  Martin Maechler  <maechler@stat.math.ethz.ch>
8    
9            * man/colSums.Rd: separately document colSums() etc, since these
10            have the extra argument 'sparseResult'.

13    
14            * R/sparseMatrix.R (spMatrix): utility (T)sparse Matrix constructor;
15            * man/spMatrix.Rd: docu., including examples
16    
17            * R/Auxiliaries.R (sp.colMeans): etc, using a patched callGeneric(),
18            in order to make colMeans() etc fast *and* correct.
19            * R/sparseVector.R (replSPvec): "[<-" functionality for
20            sparseVectors; tested in
21            * tests/simple.R:

135    
136            * R/bind.R: change tests from cbind() to cBind() and similarly to rBind()
137            * R/bind.Rout.save: ditto
