R Documentation

Align variables in time

Description

Offset variables in time to account for lags in sensor responses. Variables are interpolated so offsets do not need to be multiples of the scan interval.

Usage

align_var(
  x,
  variables = "temperature",
  offset = -0.5,
  interp_method = "linear",
  na_rm = FALSE
)

Arguments

`x`	ctd object
`variables`	Character vector of data variable names to offset.
`offset`	Numeric vector of offsets (in seconds) to add.
`interp_method`	Method for interpolating data when offsets are not a multiple of the scan interval (e.g., interpolation is necessary for a 0.55 second offset if an instrument has a 0.25 second scan interval). See ?approx
`na_rm`	Remove scans with NAs in variable channel(s) after alignment.
