griddata objects {wavethresh} | R Documentation |
Data interpolated to a grid objects.
Description
These are objects of classes
griddata
These objects store the results of interpolating a 1-D regression data set to a grid which is a power of two in length
Details
The help page for makegrid
and Kovac, (1997), p.81 give further details about how a griddata
object is constructed.
Value
The following components must be included in a legitimate griddata object.
gridt |
a vector containing the values of the grid on the "x" axis. |
gridy |
a vector containing the values of the grid on the "y" axis. This vector has to be the same length as gridt. Typically the values in ( |
G |
Codes the value of the linear interpolant matrix for the corresponding entry in |
Gindex |
Each entry in |
GENERATION
This class of objects is returned from the makegrid
function to represent the results of interpolating a 1-D regression data set to a grid.
METHODS
The griddata
class of objects really on has one function that uses it: irregwd
.
