Low-pass filter

Description

Low-pass filter variables based on time using the filter from SBE data processing.

Usage

lowpass_filter(
  x,
  variables = c("temperature", "conductivity", "pressure"),
  time_constant = c(0.5, 0.5, 1),
  precision = c(4, 6, 3),
  freq_n = NULL
)

Arguments

`x`	ctd object
`variables`	Character vector of data variable names to filter.
`time_constant`	Numeric vector of time constants for filters (in seconds).
`precision`	Numeric vector indicating how many significant digits to use for each channel.
`freq_n`	Optional. Sampling interval in seconds (1L numeric). Sampling interval is inferred from timeS if not provided.
