optimal_span {phenocamr} | R Documentation |
Calculates the optimal span for a loess spline
Description
The optimal span is calculated based upon the bayesian information criterion (BIC).
Usage
optimal_span(
y,
x = NULL,
weights = NULL,
step = 0.01,
label = NULL,
plot = FALSE
)
Arguments
y |
a vector with measurement values to smooth |
x |
a vector with dates / time steps |
weights |
optional values to weigh the loess fit with |
step |
span increment size |
label |
title to be used when plotting function output |
plot |
plot visual output of the optimization routine |
Value
Returns an optimal span to smooth a provided vector using the 'loess()' smoother.
Examples
## Not run:
# Internal function only, should not be used stand-alone.
l <- sin(seq(1,10,0.01))
l <- l + runif(length(l))
optimal_span(l, plot = TRUE)
