made sure that Lagged checks early if the argument inherits from
"acf". This fixes errors in R-devel checks of lagged (R-devel from
2021-12-03 or earlier), since now is.vector gives TRUE for objects from S3
class "acf", while previously it returned FALSE.
removed travis settings.
improved handling of "[[" for Lagged2d objects.
for Lagged2d objects, added "[" methods for character i.
added the missing show() method for Lagged2d objects.
added [[ method for slMatrix objects.
new as() method to convert matrix to slMatrix.
the initialisation method for FlexibleLagged now matches argument data
only if it is named, i.e. when explicitly supplied. This puts it in line with
the default initialisation methods and, in particular, makes it easier to
initialise subclasses of FlexibleLagged.
set a prototype, new("Lagged1d"), for the data slot of FlexibleLagged. The
default prototype was giving invalid objects in some cases,
e.g. new("FlexibleLagged").
added "maxLag<-" method for FlexibleLagged objects.
the "[[" and "[" methods for FlexibleLagged were not completely in line with
the other Lagged classes (and the documentation) for index of length one.
for "Lagged2d" objects indexing with two indices is now defined and works
naturally in a matrix-like way: the first index, i, takes values in 1:d,
where d is the number of seasons and the second index, j, in
0:maxlag. As for matrices, an empty index designates the whole range in the
corresponding extent.
Bug-fix: nSeasons() and nSeasons<-()are now exported.
new functions sl2acfbase(), acfbase2sl() and sl2vecacf() for converting
between (multivariate) autocovariances returned by stats::acf() and
season-lag representation. (These functions were formerly in package pcts.)
The title of the vignette and the keywords were wrong.
added the pkgdown site to DESCRIPTION.
New generics nSeasons() and nSeasons<-() (moved here from package sarima).
New slMatrix function and class (moved from package pcts).
Numerous changes to the documentation.
Lagged classes now have methods for "Maths" group generic.
Lagged classes now have methods for "Summary" group generic.
Lagged classes now have methods for "Ops" unary operators (binary Ops were already available).
New vignette Guide_lagged (first draft).
New function maxLag<-() with methods for Lagged objects.
dataWithLagNames(), mainly for programming.
