Plot predictions for GAMs against day of year

Usage

show_prddoy(mod, ylab, yromit = NULL, size = 0.5, alpha = 1, base_size = 11)

Arguments

mod: input model object as returned by anlz_gam
ylab: chr string for y-axis label
yromit: optional numeric vector for years to omit from the plot, see details
size: numeric indicating line size
alpha: numeric from 0 to 1 indicating line transparency
base_size: numeric indicating base font size, passed to theme_bw

Value

A ggplot object

Details

The optional yromit vector can be used to omit years from the plot. This may be preferred if the predicted values from the model deviate substantially from other years likely due to missing data.

Examples

library(dplyr)

# data to model
tomod <- rawdat %>%
  filter(station %in% 34) %>%
  filter(param %in% 'chl')

mod <- anlz_gam(tomod, trans = 'log10')

show_prddoy(mod, ylab = 'Chlorophyll-a (ug/L)')
