- group generics: "Arith", but also "Ops" and "Math"; see |
- group generics: "Arith" (partly done), |

?Math.data.frame and the examples in |
but also "Compare", "Math" etc; |

- check to see if the .onLoad function to require the methods package |
|
|
(in the AllClass.R file) is needed |
|
|
|
|
|
- Should the uplo and diag slots continue to be stored as character? |
|
|
An alternative is to use a factor as in the enum values for the |
|
|
cblas. |
|
|
|
|
|
- Organization of the source code files - right now they are organized |
|
|
according to class (e.g. dgeMatrix.R, dgeMatrix.h, dgeMatrix.c). Is |
|
|
there a better way? |
|

|
- methods for rbind and cbind where they make sense |
| 11 |
|
|
| 12 |
|
- consider moving alloc3Darray from ./src/Mutils.c to |
| 13 |
|
$(RSRC)/src/base/array.c |
| 14 |
|
|
| 15 |
|
- data/ : names 'mm' and even more 'y' are ``too short''. |
| 16 |
|
If we really want to keep them, don't use "LazyData" |
| 17 |
|
(such that one needs data(*) explicitly); |
| 18 |
|
But MM would rather want something like ex.mm and ex.y |
| 19 |
|
|
| 20 |
|
- slot "factors" maybe should move up to "Matrix" |
| 21 |

------- |
| 23 |
|
|
| 24 |
|
We have a (at least one) basic problem : |
| 25 |
|
Currently the show() method fail sometime after coercion: |
| 26 |
|
e.g. 'sy' show()s wrongly, even though it "str()" fine : |
| 27 |
|
|
| 28 |
|
(po <- crossprod(Matrix(0:3, 2))) # ok |
| 29 |
|
(ge <- as(po, "dgeMatrix")) # ok |
| 30 |
|
(sy <- as(po, "dsyMatrix")) # BAD |
| 31 |
|
str(sy) # looks fine |
| 32 |
|
|
| 33 |
|
or |
| 34 |
|
example(expand) # -> ex$L and ex$U look bad, however |
| 35 |
|
as(ex$L, "dgeMatrix") # `works' |
| 36 |
|
|
| 37 |
|
{Of course, we don't need a workaround but must understand |
| 38 |
|
and solve the problem} |
| 39 |

|
| 42 |
|
- provide methods for "dspMatrix" and "dppMatrix"! |
| 43 |
|
|
| 44 |
|
- implement (more) methods for supporting "packed" (symmetric / triangular) |
| 45 |
|
matrices; particularly something like pack() and unpack() [to/from our |
| 46 |
|
classes from/to "numeric"] --- have already man/unpack.Rd but no method yet! |
| 47 |
|
|
| 48 |
|
- implement diagonal Matrix class "ddiMatrix" etc |
| 49 |
|
using constructor function Diagonal() or Diag(). |
| 50 |
|
|
| 51 |
|
--- |
| 52 |
|
|
| 53 |
|
- combine the C functions for multiplication by special forms and |
| 54 |
|
solution wrt special forms by using a 'right' argument and a |
| 55 |
|
'classed' argument. |
| 56 |
|
[done with dgeMatrix_matrix_mm(); not yet for other classes; |
| 57 |
|
and for _crossprod()] |
| 58 |
|
|
| 59 |
|
- add more comprehensive examples / tests for Schur decomposition |
| 60 |
|
|
| 61 |
|
- arithmetic for sparse matrices: |
| 62 |
|
<sparseMatrix> o { <scalar> | <same-dim-sparseMatrix> } |
| 63 |
|
should return a sparse matrix for at least "+" and "*" , also %%, |
| 64 |
|
and "/" and "%/%" at least when the RHS is non-zero a scalar. |
| 65 |
|
|
| 66 |
|
--- |
| 67 |
|
|
| 68 |
|
- in lmer.c check all instances of the use of ZtX and XtX and change |
| 69 |
|
them so that having a negative last element of nc means use the |
| 70 |
|
response only (but look for it in the right place). |
