plotGSIMtimeseries: Plot a GSIM time series

In messamat/globalIRmap: What the Package Does (One Line, Title Case)

Description

Creates a plot of monthly discharge (m^3/s) for a GSIM gauging stations Save plot to png if path is provided.

Usage

plotGSIMtimeseries(
  GSIMgaugestats_record,
  outpath = NULL,
  maxgap = 366,
  showmissing = FALSE
)

Arguments

GSIMgaugestats_record	a data containing structure with a column called "path" towards a standard montly GSIM text file containing. In this project, e.g. the output from comp_GSIMdurfreq.
outpath	(character) path for writing output png plot (default is no plotting).
maxgap	(integer) threshold number of missing daily records to consider a calendar year unfit for analysis.
showmissing	(logical) whether to show records in years with number of missing daily records beyond maxgap.

Details

Daily streamflow records from GSIM stations are unavailable. Therefore, the graph shows the following:

• The y-axis is square-root transformed.

• Blue points: mean monthly discharge

• Light blue background shading: mean ± 2SD monthly discharge

• Black points: minimum and maximum monthly discharge

• Red points show minimum monthly discharge values equal to 0

• Purple points show months for which all daily discharge values are equal to 0.

Value
