R Documentation

Bin average: Average variables by depth/pressure bin

Description

Calculate averages for variables by depth or pressure bin.

Usage

bin_average(
  x,
  by = "depth",
  bin_width = 1,
  exclude_surface = 0.5,
  exclude_bad_flag = TRUE,
  interpolate_missing = TRUE,
  missing_latitude = 55
)

Arguments

`x`	ctd object
`by`	Grouping variable as a character vector ("depth" or "pressure")
`bin_width`	Width of bins to use for binning.
`exclude_surface`	Depth or pressure (down is positive) as numeric vector (1L). Scans will be excluded from binning if they are shallower this threshold.
`exclude_bad_flag`	Logical indicating whether to remove scans with a bad (negative) flag.
`interpolate_missing`	Interpolate variables when there are no good data for a depth/pressure bin.
`missing_latitude`	Latitude in decimal degrees to use for depth estimation if ctd object does not contain latitude.
