ldenseMatrix.R
#### "ldenseMatrix" - virtual class of logical dense matrices
#### ------------
#### Contains lge*; ltr*, ltp*; lsy*, lsp*; ldi*
## Logical -> Double {of same structure}:
setAs("lgeMatrix", "dgeMatrix", function(from) l2d_Matrix(from, "lgeMatrix"))
setAs("lsyMatrix", "dsyMatrix", function(from) l2d_Matrix(from, "lsyMatrix"))
setAs("lspMatrix", "dspMatrix", function(from) l2d_Matrix(from, "lspMatrix"))
setAs("ltrMatrix", "dtrMatrix", function(from) l2d_Matrix(from, "ltrMatrix"))
setAs("ltpMatrix", "dtpMatrix", function(from) l2d_Matrix(from, "ltpMatrix"))
### NOTA BENE: Much of this is *very* parallel to ./ndenseMatrix.R
### ~~~~~~~~~~~~~~~~
## all need be coercable to "lgeMatrix":
setAs("lsyMatrix", "lgeMatrix", function(from)
.Call(lsyMatrix_as_lgeMatrix, from, 0:0))
setAs("ltrMatrix", "lgeMatrix", function(from)
.Call(ltrMatrix_as_lgeMatrix, from, 0:0))
setAs("ltpMatrix", "lgeMatrix",
function(from) as(as(from, "ltrMatrix"), "lgeMatrix"))
setAs("lspMatrix", "lgeMatrix",
function(from) as(as(from, "lsyMatrix"), "lgeMatrix"))
## and the reverse
setAs("lgeMatrix", "ltpMatrix",
function(from) as(as(from, "ltrMatrix"), "ltpMatrix"))
setAs("lgeMatrix", "lspMatrix",
function(from) as(as(from, "lsyMatrix"), "lspMatrix"))
## packed <-> non-packed :
setAs("lspMatrix", "lsyMatrix",
function(from)
.Call(lspMatrix_as_lsyMatrix, from, 0:0))
setAs("lsyMatrix", "lspMatrix",
function(from)
.Call(lsyMatrix_as_lspMatrix, from, 0:0))
setAs("ltpMatrix", "ltrMatrix",
function(from)
.Call(ltpMatrix_as_ltrMatrix, from, 0:0))
setAs("ltrMatrix", "ltpMatrix",
function(from)
.Call(ltrMatrix_as_ltpMatrix, from, 0:0))
### -> symmetric :
if(FALSE) ## not sure if this is a good idea ... -- FIXME?
setIs("lgeMatrix", "lsyMatrix",
test = function(obj) isSymmetric(obj),
replace = function(obj, value) { ## copy all slots
for(n in slotNames(obj)) slot(obj, n) <- slot(value, n)
})
### Alternative (at least works):
setAs("lgeMatrix", "lsyMatrix",
function(from) {
if(isSymmetric(from))
new("lsyMatrix", x = from@x, Dim = from@Dim,
Dimnames = from@Dimnames, factors = from@factors)
else
stop("not a symmetric matrix; consider forceSymmetric() or symmpart()")
})
setAs("lgeMatrix", "ltrMatrix",
function(from) {
if(isT <- isTriangular(from))
new("ltrMatrix", x = from@x, Dim = from@Dim,
Dimnames = from@Dimnames, uplo = .if.NULL(attr(isT, "kind"), "U"))
## TODO: also check 'diag'
else stop("not a triangular matrix")
})
### ldense* <-> "matrix" :
## 1) "lge* :
setAs("lgeMatrix", "matrix",
function(from) array(from@x, dim = from@Dim, dimnames = from@Dimnames))
setAs("matrix", "lgeMatrix",
function(from) {
new("lgeMatrix",
x = as.logical(from),
Dim = as.integer(dim(from)),
Dimnames = .M.DN(from))
})
## 2) base others on "lge*":
setAs("matrix", "lsyMatrix",
function(from) as(as(from, "lgeMatrix"), "lsyMatrix"))
setAs("matrix", "lspMatrix",
function(from) as(as(from, "lsyMatrix"), "lspMatrix"))
setAs("matrix", "ltrMatrix",
function(from) as(as(from, "lgeMatrix"), "ltrMatrix"))
setAs("matrix", "ltpMatrix",
function(from) as(as(from, "ltrMatrix"), "ltpMatrix"))
## Useful if this was called e.g. for as(*, "lsyMatrix"), but it isn't
setAs("matrix", "ldenseMatrix", function(from) as(from, "lgeMatrix"))
setAs("ldenseMatrix", "matrix", ## uses the above l*M. -> lgeM.
function(from) as(as(from, "lgeMatrix"), "matrix"))
## dense |-> compressed :
setAs("lgeMatrix", "lgTMatrix",
function(from) as(.dense2C(from), "lgTMatrix"))
setAs("lgeMatrix", "lgCMatrix",
function(from) as(as(from, "lgTMatrix"), "lgCMatrix"))
setMethod("as.logical", signature(x = "ldenseMatrix"),
function(x, ...) as(x, "lgeMatrix")@x)
###----------------------------------------------------------------------
setMethod("diag", signature(x = "ltrMatrix"),
function(x, nrow, ncol) .Call(ltrMatrix_getDiag, x))
setMethod("diag", signature(x = "ltpMatrix"),
function(x, nrow, ncol) .Call(ltpMatrix_getDiag, x))
setMethod("diag", signature(x = "ldenseMatrix"),
function(x, nrow, ncol) diag(as(x, "lgeMatrix")))
setMethod("diag", signature(x = "ndenseMatrix"),# << the "same"
function(x, nrow, ncol) diag(as(x, "ldenseMatrix")))
setMethod("diag", signature(x = "lgeMatrix"),
function(x, nrow, ncol) .Call(lgeMatrix_getDiag, x))

setMethod("t", signature(x = "ltrMatrix"), t_trMatrix)
setMethod("t", signature(x = "lsyMatrix"), t_trMatrix)
setMethod("t", signature(x = "ltpMatrix"),
function(x) as(t(as(x, "ltrMatrix")), "ltpMatrix"))
setMethod("t", signature(x = "lspMatrix"),
function(x) as(t(as(x, "lsyMatrix")), "lspMatrix"))
## NOTE: "&" and "|" are now in group "Logic" c "Ops" --> ./Ops.R
## "!" is in ./not.R
setMethod("as.vector", signature(x = "ldenseMatrix", mode = "missing"),
function(x, mode) as(x, "lgeMatrix")@x)
setMethod("all", signature(x = "lsyMatrix"),
function(x, ..., na.rm = FALSE)

## Note: the above "lsy*" method is needed [case below can be wrong]
setMethod("all", signature(x = "ldenseMatrix"),
function(x, ..., na.rm = FALSE) {
if(prod(dim(x)) >= 1)
(!is(x, "triangularMatrix") && !is(x, "diagonalMatrix") &&
all(x@x, ..., na.rm = na.rm))
else all(x@x, ..., na.rm = na.rm)
})
## setMethod("any", ) ---> ./lMatrix.R
## setMethod("any", signature(x = "ldenseMatrix"),
## function(x, ..., na.rm = FALSE)
## (prod(dim(x)) >= 1 && is(x, "triangularMatrix") && x@diag == "U") ||
## any(x@x, ..., na.rm = na.rm))
setMethod("norm", signature(x = "ldenseMatrix", type = "character"),

.Call(dgeMatrix_norm, as(as(x,"dMatrix"),"dgeMatrix"), type),
