4987 6708 d 15 h maechler /trunk/Matrix/ back-compatibility: as(., "dsCMatrix") with one warning per session  
4720 6925 d 7 h maechler /trunk/Matrix/ image() new defaults + docs; misc  
4483 6977 d 18 h maechler /trunk/Matrix/ colSums, ... rowMeans for all Matrices; notably sparse ones via [diln]gCMatrix_colSums C code  
4463 6981 d 11 h bates /trunk/Matrix/ Don't need an interactions class. Use the row names to store the levels - duh  
4460 6981 d 16 h bates /trunk/Matrix/ added lm.fit.sparse (unexported), coercion of "factor" to dgCMatrix and dgCMatrix_cholsol  
3933 7209 d 17 h maechler /trunk/Matrix/ another set of fixes/improvements; the last prompted by Harri Kiiveri  
3931 7212 d 17 h maechler /trunk/Matrix/ miscellaneous "fixes" mostly in ChangeLog and/or related to diagonalMatrix  
3755 7258 d 12 h maechler /trunk/Matrix/ new nMatrix and subclasses; lsparse change to have x slot; many consequences  
3520 7271 d 12 h bates /trunk/Matrix/ Promotion of %*% and solve to RHS of ddenseMatrix  
3502 7275 d 7 h bates /trunk/Matrix/ Move methods to the CsparseMatrix class  
3422 7283 d 12 h bates /trunk/Matrix/ Added solve methods for dgCMatrix and documentation  
3420 7283 d 20 h bates /trunk/Matrix/ add sparse LU and QR decompositions  
3340 7309 d 16 h maechler /trunk/Matrix/ many method cleanups; notably some "dgC" -> "Csparse" generaliztations  
3310 7321 d 18 h maechler /trunk/Matrix/ miscellaneous small things, including extended tests; see also ChangeLog  
3218 7354 d 1 h maechler /trunk/Matrix/ implemented all 4 of {rowSums(), ... colMeans()}  
3175 7368 d 20 h maechler /trunk/Matrix/man/ start massive use of \linkS4class{.}  
3034 7423 d 15 h maechler /trunk/Matrix/ coercions from dgC to triangular (dtC) and symmetric (dsC), etc  
2357 7440 d 20 h maechler /trunk/Matrix/ sparse: "[<-" and better arithmetic; other tweaks  
2255 7489 d 18 h maechler /trunk/Matrix/ Class cleanup; particularly ldense* ones  
1909 7597 d 14 h maechler /trunk/Matrix/ more examples; update
