racircalcheck: Allows visual checking of rapid A/Ci response (RACiR)...

In jstinzi/racir: Rapid A/Ci Response (RACiR) Data Analysis

Description

racircalcheck Used to check range of calibration file. Produces diagnostic graphs of A vs. Ci for quality control. Output includes plots for checking and confirming cutoff values, and a plot with the fit, as well as information as to which polynomial fit the data best.

Usage

racircalcheck(
  data,
  mincut,
  maxcut,
  varnames = list(A = "A", Ca = "Ca", CO2_r = "CO2_r", E = "E", gtc = "gtc")
)

Arguments

data	Data frame with the calibration (empty chamber) rapid A/Ci response
mincut	Minimum cutoff value for reference CO2 (CO2_r). Used to cut out the data from the initial chamber mixing. Default value is set to the minimum COR_r value.
maxcut	Maximum cutoff value for reference CO2 (CO2_r). Used to cut out the data from the end of the response. Not needed in all cases. Default value is set to the maximum COR_r value.
varnames	Variable names - this allows for the use of this code with other machines and setups where variable names may differ.

Value

racircalcheck allows visual checking of RACiR calibration data

Examples

#Read in the file
data <- read_6800(system.file("extdata", "cal", package = "racir"))
#Run calibration check
racircalcheck(data = data,
              mincut = 350,
              maxcut = 780)
