Every channel here counts downloads, so the channels can be stacked and summed for one period. Each channel counts in its own way and covers a different span of years, so read a sum as a rough total, and read a rise where a channel begins as that channel starting, not as growth. Weeks start on Monday. A first or last week or month that the channel does not cover in full is left out, so every point is a whole period. Days with no record add nothing to their week or month. For a little-used package that is usually a day with no downloads, but it can also be a gap in collection.

no calls to or from another: `src/SuiteSparse/CHOLMOD/SuiteSparse_metis/include`. The whole package has 1,505 function names in 244 files and 2,490 calls between them. Most calls between files: `R/Auxiliaries.R` and `R/Ops.R` (43 calls), `src/coerce.c` and `src/objects.c` (36 calls), `R/Auxiliaries.R` and `R/subassign.R` (28 calls), `R/coerce.R` and `R/zzz.R` (26 calls), `src/coerce.c` and `src/utils.c` (22 calls). Graph: the whole call graph has 1,278 function names that take part in a call and 2,490 calls between them, set out in 17 layers with callers before what they call. Of these calls, 24 close a loop and run the other way. 227 function names have no calls and are left out. Called by the most functions: `gk_free` (75), `newObject` (62), `gk_errexit` (54), `iwspacemalloc` (44), `.M.kind` (29). Calling the most functions: `CHOLMOD` (45), `main` (32), `internal_function` (28), `sparse_as_Csparse` (19), `METIS_NodeND` (19).

Memory - Warnings newly reported by `rchk` are squashed. Bug Fixes - `Matrix` version 1.7-3 renamed four macros defined in `inst/include/Matrix/version.h`, stripping the `R_` prefix of the original names `R_MATRIX_PACKAGE_*`. This change was accidental and is reverted. - Ported typo fix in `Intro2Matrix.Rnw` from trunk. --- R Observatory is independent of the R Project, CRAN and Bioconductor. The same page for people is at /cran/Matrix, and every address is listed at /llms.txt.
