Fixed ‘LaTeX specials’ note from CRAN.

Minor documentation tweaks.

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`

.

- updated the vignette.

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.

- New function
`dataWithLagNames()`

, mainly for programming.

- First CRAN version (taken out of package sarima).
