NEW FEATURES
o new target for R installation testing : make strict-tests.
o symnum(x) now nicely codes logical x.
o convolve() has a new type = c("circular", "open", "filter")
argument allowing more than the only circular convolution.
o par(xpd) now has three settings: FALSE (clip to plot region),
TRUE (clip to figure region), or NA (clip to device region).
o zapsmall(x) works for complex x.
o new global variable R.version.string (for plots & reports).
Deprecated version & Version for new R.version & R.Version.
o R CMD Rd2dvi has builtin "Usage" help and works for multiple files.
Useful for automatic reference manual of a package.
(doc/manual/lib2tex is more efficient for installed packages, however).
BUG FIXES
o power() is now fully implemented and documented.
o A couple of problems with group generic operations.
o A bug which meant that it was not possible to add elements
to zero length lists in the obvious way has been fixed.
x <- list(); x[[1]] <- 10
x <- list(); x[["a"]] <- 11
both now work.
o save.image() ignored dot-names. (esp. .First())
o lab= argument to plot() misinterpreted by axis() via ... passing
o NULL labels in text() caused segfault
o matrix(f,...) with f a factor now coerces to character
o documentation errors for substitute and is.vector, minor fixups for
trig and nlm
o Background colours are set properly on X11 devices with
colortype="pseudo": sometimes they were not allocated separately.
o C() works (again?) for a single argument.
o is.na() didn't work properly for "list" arguments.
o symnum() sometimes failed with arrays of rank >= 3.
o in some cases one could get nonblack color instead of
black on 2nd x11() window.
o influence.measures(.) $ is.influential was wrong on the
cooks.distance.
o printing of complex NaN/Inf was wrong as well.
o printing of complex named vectors had a wrong initial space.
o allow trailing space in character->numeric coercion
o library() gave wrong "masked" warnings in some cases.
o par(xpd) semantics were not compatible with S.
o rect() output was not clipped in PostScript.
o par(pin=c(width, height)) was behaving as par(pin=c(width, width)).
o Non-blank separated data files didn't have their 1st field
handled properly.
o "aux" directory moved to "tools" to avoid difficulties on
Windows.
o structure() clobbered factors with missing levels.
o pmatch() misbehaved on duplicate matches.
o R CMD Rd2dvi <file.Rd> works again.
o logical binops tried to set time series parameters before dimensions.
o upped the BUFSIZE in model.c (NOT proper long-term solution).
o dput(), dump() and deparse() now always use DBL_DIG (=15) digits
for numeric formatting.
o chull() now works for vertical borders, such as in chull(c(1,1,2),3:1).
toolkit that efficiently solves systems of linear equalities and
inequalities, into the NetBSD packages collection.
Constraints may be either requirements or preferences. Client code
specifies the constraints to be maintained, and the solver updates the
constrained variables to have values that satisfy the constraints.
Version 0.50 of the solving toolkit adds support for a one-way finite
domain subsolver.
Notable changes are:
* Implemented MDETERM and MINVERSE matrix functions.
* Finished the ROMAN function completing the mathematical
functions.
* Implemented DB, DDB, FREQUENCY, QUARTILE, and XNPV functions.
* Fixed DOLLAR, DOLLARDE, DOLLARFR, and PROB functions.
* Added GUI for Summary Info.
* Enabled function wizard.
* Initial stab at Lotus 123: 'wk1', 'wks' import.
* Added GUI for Names.
* Better Excel string importing.
* Fix for padded number insertion ( fixes CSV import )
* Implemented ISREF, INDIRECT improved CELL
* Fixed several database functions.
* Non-relative R1C1 style references.
* Enable Array formulas.
* Add VALUE_BOOLEAN, VALUE_ERROR, and OPER_PERCENT
* Added EOMONTH, WORKDAY, NETWORKDAYS.
* Work on functions : ROW, COLUMN, ISLOGICAL, ISERR, ISBLANK,
DATEVALUE
* Support implict intersection 'feature' of XL for functions,
NOT operators.
* Support Ctrl-Arrow movement & selection. Make moving corner of
selection visible.
* Support F4 switching between absolute and relative addressing
modes
* Reworked internal handling of absolute/relative addressing.
* Fixed cut/copy/paste to relocate relative references to only
when copying not cuting.
* Implemented BESSELI, BESSELK completing the engineering functions.
* Added Moniker support for the Workbooks
* Added a signal for cell_content_changed for the speech support.
* Fixed locale setting and switching for file IO.
* Updated the CORBA interface for setting cell attributes.
* Scrolling sheet tabs.
* Many translations updated, thanks to our translators.
* innumerable minor bugs fixed.
