spreadPaleoData

A function to interpolate paleoData_values to a new vector using a nearest neighbor interpolation.

spreadPaleoData(
  age,
  value,
  newAge = NA,
  spreadBy = NA,
  spreadMax = NA,
  spreadMaxPct = NA,
  minAge = -75,
  maxAge = NA
)

Arguments

age

age vector for original timeseries

value

paleoData vector to spread

newAge

new age vector to spread over. If NA, this will be estimated using seq(min(age), max(age), spreadBy)

spreadBy

if newAge is not supplied, what is the desired resolution of the spread values? If NA, the minimum age gap divided by 5 will be used

spreadMax

a limit to how many years a value can be interpolated across (given in years). If NA, no limit is imposed.

spreadMaxPct

a limit to how many years a value can be interpolated across (given in the quantile ranking of age gaps (0.5=the median age gap). A floor of 1 year is imposed). If NA, no limit is imposed. Superseded by maxGap

minAge

minimum age value for output age vector. Default is -75 cal yr BP (2025 CE)

maxAge

maximum age value for output age vector. If NA, this will be the max(age) plus half the gap between the two oldest ages

Value

list of length=2 (spreadAge and spreadVal numeric vectors)
