CHANGES IN spatstat.sparse VERSION 3.1-0
OVERVIEW
o Internal improvements.
CHANGES IN spatstat.sparse VERSION 3.0-3
OVERVIEW
o Minor improvements.
CHANGES IN spatstat.sparse VERSION 3.0-2
OVERVIEW
o We thank Joey Arthur for contributions.
o Bug fix.
BUG FIXES
o marginSumsSparse
If the result of marginSumsSparse was a one-dimensional sparse vector,
the entries were incorrectly rearranged so that the non-zero entries
were all at the beginning of the vector.
[Spotted by Joey Arthur.]
Fixed.
CHANGES IN spatstat.sparse VERSION 3.0-1
OVERVIEW
o Minor changes to package information.
CHANGES IN spatstat.sparse VERSION 3.0-0
OVERVIEW
o Minor internal changes.
CHANGES IN spatstat.sparse VERSION 2.1-1
OVERVIEW
o Bug fix.
BUG FIXES
o matrixsqrt, matrixinvsqrt, matrixpower
If the result was a complex-valued matrix,
the values were completely incorrect.
Fixed.
CHANGES IN spatstat.sparse VERSION 2.1-0
OVERVIEW
o Join two sparse arrays.
o Minor improvements and bug fixes.
NEW FUNCTIONS
o bind.sparse3Darray
Join two sparse three-dimensional arrays along a specified dimension
(analogously to 'rbind', 'cbind' or 'abind') to make another
sparse three-dimensional array.
SIGNIFICANT USER-VISIBLE CHANGES
o quadform
Argument 'v=NULL' is now accepted, and interpreted as the identity matrix.
o bilinearform
Argument 'v=NULL' is now accepted, and interpreted as the identity matrix.
BUG FIXES
o quadform
Crashed if 'v' was missing.
Fixed.
CHANGES IN spatstat.sparse VERSION 2.0-0
OVERVIEW
o Package adjusted to conform to the spatstat family.
o New function 'gridadjacencymatrix'.
NEW FUNCTIONS
o gridadjacencymatrix
Given the dimensions of a rectangular grid of points,
create the adjacency matrix for the corresponding neighbourhood
graph, whose vertices are the grid points, and whose edges are the
joins between neighbouring grid points. The result is a sparse matrix.
CHANGES IN spatstat.sparse VERSION 1.3-1
OVERVIEW
o Internal adjustments.
CHANGES IN spatstat.sparse VERSION 1.3-0
OVERVIEW
o Some code has been transferred to spatstat.utils.
SIGNIFICANT USER-VISIBLE CHANGES
o RelevantNA, RelevantZero, RelevantEmpty, grokIndexVector
These functions have been moved to the package 'spatstat.utils'.
CHANGES IN spatstat.sparse VERSION 1.2-1
OVERVIEW
o Internal bug fix.
CHANGES IN spatstat.sparse VERSION 1.2-0
OVERVIEW
o Efficiency improvement
SIGNIFICANT USER-VISIBLE CHANGES
o spatstat.sparse
Code should run faster; we have reduced the overheads in executing C code.
CHANGES IN spatstat.sparse VERSION 1.1-1
OVERVIEW
o Internal code improvements.
CHANGES IN spatstat.sparse VERSION 1.1-0
OVERVIEW

OVERVIEW
o More support for complex values
SIGNIFICANT USER-VISIBLE CHANGES
o sumouter, quadform, bilinearform
These functions now handle complex-valued matrices and vectors.
o marginSumsSparse
This function now handles complex-valued sparse arrays.
CHANGES IN spatstat.sparse VERSION 1.0-4
OVERVIEW
o spatstat.sparse now 'requires' the Matrix package.
SIGNIFICANT USER-VISIBLE CHANGES
