Creates an anomaly timeseries from a climatology — make_2d_anomaly

This function calculates a timeseries anomaly by subtracting a reference climatology from an input timeseries dataset. It standardizes dataframe and RDS file inputs and either returns a list of anomaly dataframes to the R environment or writes them directly to disk.

Usage

make_2d_anomaly_ts(
  data.in,
  climatology,
  write.out = FALSE,
  output.files = NULL
)

Arguments

data.in: character vector, list, or data.frame. Single file path, vector of file paths, single data.frame, or list of data.frames representing the raw timeseries data.
climatology: data.frame. A dataframe with the same time dimensions and area names as data.in to act as a climatological reference.
write.out: logical. If TRUE, writes an RDS file. If FALSE, returns a list of data.frames. Default is FALSE.
output.files: character vector. Full output file names corresponding to each input file. Required if write.out is TRUE. Default is NULL.

Value

A list of anomaly data.frames if write.out is FALSE, or writes RDS files to disk if TRUE.
