Plot method for object of class ‘met’

Description

Some plots are similar to APSIM, others are different and more useful in some respects

Usage

## S3 method for class 'met'
plot(
  x,
  ...,
  years,
  met.var,
  plot.type = c("ts", "area", "col", "density", "anomaly"),
  cumulative = FALSE,
  facet = FALSE,
  climatology = FALSE,
  summary = FALSE
)

Arguments

x	object of class ‘met’
...	additional arguments. None used at the moment.
years	optional argument to subset years
met.var	optional argument to choose a certain variable. By default, temperature (min and max) is displayed
plot.type	type of plot, default is ‘ts’ or time-series. The options ‘area’ and ‘col’ are only available when summary = TRUE. Option ‘density’ produces a simple plot. Option ‘anomaly’ ignores argument cumulative is treated as TRUE regardless.
cumulative	default is FALSE. Especially useful for ‘rain’.
facet	whether to display the years in in different panels (facets). Not implemented yet.
climatology	logical (default FALSE). Whether to display the ‘climatology’ which would be the average of the data. Ideally, there are at least 20 years in the ‘met’ object.
summary	whether to plot ‘summary’ data. (default FALSE).

Examples

## Read in and plot a met file
extd.dir <- system.file("extdata", package = "apsimx")
ames <- read_apsim_met("Ames.met", src.dir = extd.dir)
plot(ames, years = 2012:2015)
## Perhaps more informative
plot(ames, years = 2012:2015, cumulative = TRUE)
## for rain
plot(ames, met.var = "rain", years = 2012:2015, cumulative = TRUE)
plot(ames, met.var = "rain", years = 2012:2015, cumulative = TRUE, climatology = TRUE)
plot(ames, met.var = "rain", years = 2012:2015, plot.type = "anomaly")
## It is possible to add ggplot elements
library(ggplot2)
p1 <- plot(ames, met.var = "rain", years = 2012:2015, cumulative = TRUE)
p1 + ggtitle("Cumulative rain for 2012-2015")
