fitplot: Plot the fitted results for a tidal object

Description

Plot a tidal object to view response variable observations, predictions, and normalized results.

Usage

fitplot(dat_in, ...)
# S3 method for tidal
fitplot(
  dat_in,
  tau = NULL,
  predicted = TRUE,
  annuals = TRUE,
  logspace = TRUE,
  dt_rng = NULL,
  col_vec = NULL,
  grids = TRUE,
  min_mo = 9,
  mo_strt = 10,
  pretty = TRUE,
  lwd = 1,
  size = 2,
  alpha = 1,
  ...
)
# S3 method for tidalmean
fitplot(
  dat_in,
  predicted = TRUE,
  annuals = TRUE,
  logspace = TRUE,
  dt_rng = NULL,
  col_vec = NULL,
  grids = TRUE,
  min_mo = 9,
  mo_strt = 10,
  pretty = TRUE,
  lwd = 1,
  size = 2,
  alpha = 1,
  ...
)

Value

A ggplot object that can be further modified

Arguments

dat_in

input tidal or tidalmean object

...

arguments passed to other methods

tau

numeric vector of quantiles to plot, defaults to all in object if not supplied

predicted

logical indicating if standard predicted values are plotted, default TRUE, otherwise normalized predictions are plotted

annuals

logical indicating if plots are annual aggregations of results

logspace

logical indicating if plots are in log space

dt_rng

Optional chr string indicating the date range of the plot. Must be two values in the format 'YYYY-mm-dd' which is passed to as.Date.

col_vec

chr string of plot colors to use, passed to gradcols. Any color palette from RColorBrewer can be used as a named input. Palettes from grDevices must be supplied as the returned string of colors for each palette.

grids

logical indicating if grid lines are present

min_mo

numeric value from one to twelve indicating the minimum number of months with observations for averaging by years, applies only if annuals = TRUE. See annual_agg.

mo_strt

numeric indicating month to start aggregation years, defaults to October for USGS water year from October to September, applies only if annuals = TRUE. See annual_agg.

pretty

logical indicating if my subjective idea of plot aesthetics is applied, otherwise the ggplot default themes are used

lwd

numeric value indicating width of lines

size

numeric value indicating size of points

alpha

numeric value indicating transparency of points or lines

Examples

## load a fitted tidal object
data(tidfit)

# plot using defaults
fitplot(tidfit)

# get the same plot but use default ggplot settings
fitplot(tidfit, pretty = FALSE)

# plot in log space
fitplot(tidfit, logspace = TRUE)

# plot specific quantiles
fitplot(tidfit, tau = c(0.1, 0.9))

# plot the normalized predictions
fitplot(tidfit, predicted = FALSE)

# plot as monthly values
fitplot(tidfit, annuals = FALSE) 

# format the x-axis is using annual aggregations
library(ggplot2)

fitplot(tidfit, annual = TRUE) + 
 scale_x_date(limits = as.Date(c('2000-01-01', '2012-01-01')))

# modify the plot as needed using ggplot scales, etc.

fitplot(tidfit, pretty = FALSE, linetype = 'dashed') + 
 theme_classic() + 
 scale_y_continuous(
   'Chlorophyll', 
   limits = c(0, 50)
   ) +
 scale_colour_manual( 
   'Predictions', 
   labels = c('lo', 'md', 'hi'), 
   values = c('red', 'green', 'blue'), 
   guide = guide_legend(reverse = TRUE)
   ) 
 
# plot a tidalmean object
data(tidfitmean)

fitplot(tidfitmean)
