Calculate GAM residuals

Use GAM analysis to compute residuals. Relies on mgcv::gam to perform general additive model.

createResiduals(
  df,
  dep,
  residualModel = "doy_flw_sal",
  analySpec = analySpec,
  gamTable = FALSE,
  gamPlot = FALSE,
  flow.detrended = NA,
  salinity.detrended = NA,
  width = 10,
  height = 3.5,
  folder_r = "pltResiduals",
  ProjRoot
)

Arguments
