fts updated to be a constructor of a new S4 object that is used to create
objects of class
fts. Note that the user may specify their own basis
and grid or may specify that they want the constructor to build such
attributes automatically. In addition, the
fts may be comprised of
variables observed over one or two-dimensional domains. This constructor
also has custom validity checks built in to help the user construct
fts.plot was updated to allow for plotting of
fts variables observed
over two-dimensional domains.
fssa updated so that univariate and multivariate
fts objects may be
decomposed where each variable may be observed over a one or
two-dimensional domain. In addition, the speed of the decomposition
process was increased by using the Rspectra and RcppEigen R packages,
and the Eigen C++ package.
plot.fssa was updated to allow the user to plot the left singular
fts whose variables have domains over two-dimensions. All
other plotting options were updated to handle the two-dimensional domain
functionality as well.
freconstruct updated to allow for the reconstruction stage of
univariate and multivariate
fts objects whose variables might be
might observed over one or two-dimensional domains.
Arithmetic operations such as
fts addition and
fts subtraction have
been updated to allow for numeric vector-
fforecast was added to allow for nonparametric forecasting of
fssa recurrent or
fssa vector forecasting. The
approach begins with objects of class
fts may be
univariate or multivariate however, the variables must be observed over
a one-dimensional domain. Different dimensional domains forecasting is
Montana was added to provide an example of a multivariate
whose variables are observed over a one-dimensional and two-dimensional
load_github_data was added to allow the user to load the
Montana datasets from GitHub which significantly reduced
the size of the package. In addition, this same function may be used to
load data from any other public GitHub repository.
