7    
8            * R/pMatrix.R: as(*, "matrix") now returns 0/1 *integer* matrix,
9                    and hence does as.vector(.).
10            * man/pMatrix-class.Rd: docs
11            * R/sparseMatrix.R: fix for printing "integer sparse"
12    
13            * tests/Class+Meth.R (tstMatrixClass): test M[FALSE], M[2] etc
14    
15            * R/Matrix.R and others: use "exact" function argument list for
16                    both "["   : (x, i,j, ..., drop)
17                    and  "[<-" : (x, i,j, ..., value)
18    
19            * R/denseMatrix.R: M[i] and M[i] <- v  (i vector) now work
20            * R/Tsparse.R (replTmat):    ditto
21            * R/diagMatrix.R (replDiag): ditto
22            * R/Csparse.R (replCmat):    ditto {was it worth the pain?}
