checkSaved: Determine if combination of N, W and K is available on disk, or must be computed
Description
Given values for N, W and K, determine if the combination is
available on disk as a data() load. If so, significant time savings can be
obtained, especially for large N.
Usage
checkSaved(N, W, K)
Arguments
N
the length of the time index array, in units of deltat.
W
the time bandwidth, in units ofdf/year. This is not
the same units as a slp(...) call, and W should be an integer,
e.g., 6 df/year.
K
the number of basis vectors requested.
Value
Logical (TRUE or FALSE), indicating availability or lack thereof.
Details
Does a lookup against data(slpSavedObjects) to determine whether the
combination of N, W and K is saved on disk as part of the
package, and can be loaded. It is possible to create your own basis objects for
particular choices of N, W and K and save them as part
of the library directory, updating slpSavedObjects as you do so.
