racircalcheck_advanced Used to check range of calibration file. Produces diagnostic graphs of A vs. Ci for quality control.

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

`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.
`digits`	Specifies rounding for groups. Defaults to -2 (100s). Effectively uses 100 ppm intervals (e.g. data matching >50 ppm to 150 ppm would be assigned to an interval centered around 100 ppm for reference CO2).
`varnames`	Variable names - this allows for the use of this code with other machines and setups where variable names may differ.

racircalcheck_advanced returns a data frame with corrected RACiR data

#Read in data
data <- read_6800(system.file("extdata", "poplar_2", package = "racir"))
caldata <- read_6800(system.file("extdata", "cal", package = "racir"))
#Correct data
racircalcheck_advanced(data = data, mincut = 350, maxcut = 780)
