createResiduals function

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

• df: data frame
• dep: variable
• residualModel: which gam formula is used to compute. Default = 'doy_flw_sal'
• analySpec: analytical specifications
• gamTable: gam table setting (set to FALSE to turn off table output) Default = FALSE
• gamPlot: gam plot setting (set to FALSE to turn off plotting) Default = FALSE
• flow.detrended: data generated by detrended.flow. Default = NA
• salinity.detrended: data generated by detrended.flow. Default = NA
• width: width of png figure (inches). Default = 10
• height: height of png figure (inches). Default = 3.5
• folder_r: folder to store residual plots
• ProjRoot: Root folder for project.

Returns

Returns df with appended column of data
