Examples

## Not run: 
# Load modern pollen data
modern_pollen <- read.csv("/path/to/modern_pollen.csv")

# Extract taxa
taxaColMin <- which(colnames(modern_pollen) == "taxa0")
taxaColMax <- which(colnames(modern_pollen) == "taxaN")
taxa <- modern_pollen[, taxaColMin:taxaColMax]

fit_tf_Tmin2 <- fxTWAPLS::TWAPLS.w2(
  taxa,
  modern_pollen$Tmin,
  nPLS = 5,
  usefx = TRUE,
  fx_method = "bin",
  bin = 0.02
)

nsig <- 3 # This should be got from the random t-test of the cross validation
fxTWAPLS::plot_residuals(fit_tf_Tmin2, nsig)
