ch_flow_raster_qa {CSHShydRology}

Raster plot of daily streamflows with WSC quality flags

Description

Raster plot with WSC quality flags. This produces a plot showing the flow data in grayscale overlain by the Water Survey of Canada quality flags. Colours are consistent with ECDataExplorer. Raster layout lets the use see the flags in a different context than in a hydrograph.

Usage

ch_flow_raster_qa(DF, metadata = NULL)

Arguments

DF

dataframe of daily streamflow read by ch_read_ECDE_flows

metadata

dataframe of metadata or defaults to "HYDAT_list"

Value

Produces a raster plot: years against day of year, showing the data flags:

A

(Partial) in green

B

(Backwater) in cyan

D

(Dry) in yellow

E

(Estimated) in red

Returns TRUE if executed properly; a standard R graphic is created.
