In bmcnellis/sapflux: Analyze Sapflux Traces

Description Usage Methods (by generic) Slots

Defines the 'flux' class for use in sapflux package functions.

The 'flux' object class stores all the information relevant to an analysis of sapflux data in one form, and allows the use of seperate methods for plot, print, and summary.

## S4 method for signature 'flux'
initialize(.Object, ...)

## S4 method for signature 'flux'
plot(x, y, ...)

## S4 method for signature 'flux'
summary(object, ...)

## S4 method for signature 'flux'
identify(x, y = NULL, labels = seq_along(x), pos = FALSE,
  n = length(x), plot = TRUE, atpen = FALSE, offset = 0.5,
  tolerance = 0.25, ...)

## S4 method for signature 'flux'
head(x, n = 6L, ...)

## S4 method for signature 'flux'
str(object, ...)

initialize: Stores defaults for 'flux' class
plot: Plots flux traces sequentially using 'flux' object metadata. 'y' parameter may be ommitted to plot all columns in data, or a numeric vector of columns to plot.
summary: Display summary statistics for 'flux' objects
identify: Interactive point identification
head: Flux header information.
str: Abbreviated flux structure information.

raw_data

The raw sapflux data sourced by FluxImport. Redundant and optional.

source_files

A character vector of the filenames sourced by FluxImport, in order of import.

data

The pre- and post-processed sapflow data, with each column representing a unique probe and unique metadata identifier.

time

Time vector associated with the sapflux data.

date

As time, but for dates.

datatype

The kind of data in the 'data/raw_data' slot. Can be: voltages, temperatures, flux index, flux density, stem flux, plant flux, stand flux, or land flux.

Each data.type has processing parameter defaults, set in "./data/sapflux_datatype_defaults.csv".
