show_prddoy: Plot predictions for GAMs against day of year

Description

Plot predictions for GAMs against day of year

Usage

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

Value

A ggplot object

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

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)')
