Description Usage Arguments Details Value
Smooth calibration curve
1 | smoothCalibration(Year, PMC, smoothing.level, method = "rgr")
|
Year |
calibration data - vector of (fractional) year of atmospheric carbon measurement |
PMC |
calibration data - vector of percent modern carbon values |
smoothing.level |
(scalar) the level of smoothing to apply. The interpretation of this value depends on the method used |
method |
string specifying the smoothing method to use. Currently only "rgr" |
The function smoothCalibration
smooths
an atmospheric carbon curve. This function is experimental.
A smoothed calibration curve can be used to provide an approximation for the effect of having multiple strands in a sample of moss, each with slightly different growth rates or physical alignment within the sample. Currently the only method provided is "rgr", which effectively assumes that the sample is comprised of multiple strands, each with a constant (random) growth rate offset.
a data frame of smoothed carbon values with column names "Year" and "PMC"
