binMean1D: Bin-average f=f(x)

Description

Average the values of a vector f in bins defined on another vector x. A common example might be averaging CTD profile data into pressure bins (see “Examples”).

Usage

binMean1D(x, f, xbreaks)

Arguments

x

vector of numerical values.

f

vector of numerical values.

xbreaks

Vector of values of x at the boundaries between bins, calculated using pretty() if not supplied.

Value

A list with the following elements: the breaks (xbreaks, midpoints (xmids) between those breaks, the count (number) of x values between successive breaks, and the resultant average (result) of f, classified by the x breaks.

T <- ctd[["temperature"]]
plot(T, z)
TT <- binMean1D(z, T, seq(-100, 0, 1))
lines(TT$result, TT$xmids, col='red')
