npsp internal and secondary functions

Description

Listed below are supporting functions for the major methods in npsp.

Usage

.cpu.time.ini()

revdim(a, d)

.compute.masked(bin, cov.bin = NULL, tol.mask = npsp.tolerance(2))

.wloss(est, teor, w, loss = c("MSE", "MRSE", "MAE", "MRAE"))

## S3 method for class 'locpol.bin'
residuals(object, ...)

.kriging.simple.solve(x, newx, svm)

## S3 method for class 'np.geo'
residuals(object, ...)

## S3 method for class 'grid.par'
print(x, ...)

## S3 method for class 'grid.par'
dim(x)

## S3 method for class 'grid.par'
dimnames(x)

## S3 method for class 'grid.par'
as.data.frame(x, row.names = dimnames(x), optional = FALSE, ...)

is.data.grid(x)

## S3 method for class 'data.grid'
dim(x)

## S3 method for class 'data.grid'
dimnames(x)

.rice.rule(x, a = 2, b = 3, ...)

splot.plt(
  horizontal = FALSE,
  legend.shrink = 0.9,
  legend.width = 1,
  legend.mar = ifelse(horizontal, 3.1, 5.1),
  bigplot = NULL,
  smallplot = NULL
)

.rev.colorRampPalette(colors, interpolate = "spline", ...)

Arguments

a	scale values.
cov.bin	(optional) covariance matrix of the binned data or semivariogram model (svarmod-class) of the (unbinned) data.
object	object used to select a method: local polynomial estimate of the trend (class locpol.bin) or nonparametric geostatistical model (class extending np.geo).
...	further arguments passed to or from other methods.
x	vector/matrix with data locations (each component/row is an observation location).
newx	vector/matrix with the (irregular) locations to predict (each component/row is a prediction location). or an object extending grid.par-class (data.grid).
svm	semivariogram model (of class extending svarmod).
b	exponent values.

Value

.compute.masked returns a list with components:

mask	logical vector bin$binw > tol.mask.
w	x$binw[mask].
sw	sum(w).
hat	(optional) bin$locpol$hat[mask, mask].
cov.bin	(optional) masked (aproximated) covariance matrix of the binned data.
