smooth: Smooth a variable

In jiho/castr: Process CTD casts

Description

Smooth a variable in a cast using a weighted moving average.

Usage

smooth(x, k = 1, n = 1)

Arguments

x	vector of the variable of interest. It must have been recorded at approximately regular intervals (see slide() as to why).
k	order of the window; the window size is 2k+1.
n	number of times to smooth the data.

Value

A vector containing the smoothed variable, containing as many elements as the original variable.

See Also

slide() for the underlying implementation.

Examples

plot(-depth ~ chla, data=d)
lines(-depth ~ smooth(chla), data=d, type="l", col="red")
lines(-depth ~ smooth(chla, k=2, n=5), data=d, type="l", col="blue")
legend(1, 0, legend=c("k=1, n=1", "k=2, n=5"), col=c("red", "blue"), lty="solid")
