checkGRDCzeroes: Check zero-flow values in GRDC discharge record

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

Description

Plot and subset a given period (in days) on each side of every zero-flow period in record for a given GRDC station. The output is a plot with a panel showing discharge for each zero-flow period.

Usage

checkGRDCzeroes(
  GRDCstatsdt,
  in_GRDC_NO,
  period = 15,
  yearthresh,
  maxgap,
  in_scales = "free_x",
  labelvals
)

Arguments

GRDCstatsdt	formatted data.table including a "path" column to access GRDC standard daily discharge record text file for the gauging station of interest.
in_GRDC_NO	GRDC unique identifier of the station to be investigated.
period	(integer) number of days on each side of zero-flow values to subset.
yearthresh	(integer) minimum year from which to analyze discharge record
maxgap	(integer) threshold number of missing daily records to consider a calendar year unfit for analysis.
in_scales	(character) should panel scales be fixed ("fixed", the default), free ("free"), or free in one dimension ("free_x", "free_y")?
labelvals	(logical) whether to label individual discharge values

Value

data.table subset of GRDCstatsdt, including only records for zero-flow days +- period
