Plot Earth Temperatures

Plot the earth temperature for a given depth (degrees celsius) through time, for each chosen CliFlo station.

Usage

# S4 method for class 'cfEarthTemp,missing'
plot(
  x,
  y,
  ggtheme = c("grey", "gray", "bw", "linedraw", "light", "minimal", "classic"),
  scales = c("fixed", "free_x", "free_y", "free"),
  n_col = 1,
  ...
)

Arguments

x

a cfEarthTemp object.

y

missing.

ggtheme

character string (partially) matching the ggtheme to be used for plotting, see 'Theme Selection' below.

scales

character string partially matching the scales argument in the link[ggplot2]{facet_wrap} function.

n_col

the number of columns of plots (default 1).

...

further arguments passed to theme.

Examples

if (FALSE) { # \dontrun{
# Retrieve public earth temperature data for the last 30 days at Reefton Ews
# station, at a depth of 10cm

# Subtract 30 days from today's date to get the start date
last_month = paste(as.character(Sys.Date() - 30), 0)

reefton_earth = cf_query(cf_user(), cf_datatype(4, 3, 2), cf_station(),
                         start_date = last_month)

class(reefton_earth) # cfTemp object

# Plot the temperature data using the defaults
plot(reefton_earth)

# Enlarge the text and add the observations as points
library(ggplot2) # for element_text() and geom_point()
plot(reefton_earth, ggtheme = "bw", text = element_text(size = 16)) +
  geom_point(size = 3, shape = 1)

# Save the plot as a png to the current working directory
library(ggplot2) # for ggsave()
ggsave("my_earthTemp_plot.png")
} # }
