3543 7267 d 22 h maechler /branches/Matrix-for-R-2.3.x/ branching an "old-R" compatible version of Matrix  
3534 7268 d 23 h maechler /trunk/Matrix/ miscellaneous tweaks; moved some method definitions higher up  
3411 7285 d 20 h maechler /trunk/Matrix/R/ use Csparse_to_logical  
3340 7309 d 20 h maechler /trunk/Matrix/ many method cleanups; notably some "dgC" -> "Csparse" generaliztations  
3338 7311 d 7 h maechler /trunk/Matrix/ miscellaneous mostly related to sparse indexing  
3218 7354 d 5 h maechler /trunk/Matrix/ implemented all 4 of {rowSums(), ... colMeans()}  
3172 7370 d 6 h maechler /trunk/Matrix/ useDynlib(*, .registration=TRUE)  
3034 7423 d 18 h maechler /trunk/Matrix/ coercions from dgC to triangular (dtC) and symmetric (dsC), etc  
2357 7441 d 0 h maechler /trunk/Matrix/ sparse: "[<-" and better arithmetic; other tweaks  
2208 7496 d 18 h maechler /trunk/Matrix/ make Matrix() "smart" -- with help of quite a few new setAs(. , .) settings  
2198 7498 d 15 h maechler /trunk/Matrix/ new coercion to dtr* and dsy* using isSymmetric() and isTriangular(); fix validity checking; some class descriptions  
2120 7510 d 15 h maechler /trunk/Matrix/R/ isSymmetric() generic must match isSymmetric in R-devel  
2022 7550 d 16 h bates /trunk/Matrix/ Matrix multiplication and coersion at higher level  
1906 7597 d 18 h maechler /trunk/Matrix/R/ isSymmetric() & simulate() updates; sparse subsetting  
1888 7599 d 21 h maechler /trunk/Matrix/R/ (comments)  
1869 7604 d 21 h maechler /trunk/Matrix/ more coercions; particularly "d" <-> "l"; more tests (and more FIXMEs!); fixing two "index-0 bugs"; ...  
1833 7615 d 19 h maechler /trunk/Matrix/ too many changes: rbind2 for dM*, cbind2(), "Math", "Arith" for sparse ones; more "s/gTMatrix/TsparseMatrix/" fixes; quite a few more tests, incl some for *all* classes  
1777 7634 d 20 h maechler /trunk/Matrix/ new classes "index", "symmetricM*" and "triangularM*"; indexing for logical and character indices; new tests; more to do  
1766 7638 d 17 h maechler /trunk/Matrix/ indexing (mainly denseMatrix) - using "vector" indices  
1761 7639 d 21 h maechler /trunk/Matrix/ Version 0.98-6: "[" methods for dense matrices; first "[<-"; examples
