This function creates a facet plot to visualize ENSO and IOD data over time, with separate panels for each variable (IOD, ENSO3, ENSO34, ENSO4). A horizontal line at zero is included to indicate the neutral value, and a vertical line marks the current date, with the date displayed vertically on the left side of the line.
Arguments
- PATHS
A list containing paths where ENSO and IOD data are stored and where output figures should be saved. Typically generated by the
get_paths()function and should include:DATA_ENSO: Path to the directory containing the compiled ENSO and IOD data.
DOCS_FIGURES: Path to the directory where the output figure will be saved.
- frequency
Character; temporal resolution of the ENSO/IOD series to plot. One of
"daily","weekly", or"monthly".
Value
A ggplot facet plot showing the time series of IOD, ENSO3, ENSO34, and ENSO4 over time. The plot includes:
A horizontal solid line at zero to indicate the neutral sea surface temperature anomaly.
A vertical dashed line to indicate the current date, with the current date displayed as vertical text.
Facets for each variable, allowing for easy comparison of IOD and ENSO regions.
Details
This function uses ggplot2 to create a line plot with facets for each variable (IOD, ENSO3, ENSO34, and ENSO4). It adds a horizontal reference line at zero and a vertical line representing the current date. The current date is displayed as vertical text aligned to the left of the vertical line. The data is expected to be in a date, variable, and value format.
Examples
if (FALSE) { # \dontrun{
# Load the ENSO and IOD data and plot it
PATHS <- get_paths()
plot_ENSO_data(PATHS)
} # }
