RMevents.plotQ: RMevents.plotQ

In USGS-R/Rainmaker: Rainfall event processing

RMevents.plotQ

Description

Function to graph rainfall and flow for a given x-day window around specified event periods

Usage

RMevents.plotQ(
  df,
  dfQ,
  date = "pdate",
  Qdate = "pdate",
  rain = "rain",
  Q = "Q",
  df.events,
  sdate = "StartDate",
  edate = "EndDate",
  erain = "depth",
  plot.buffer = 3,
  logy = "",
  site.name = "",
  SampleInfo,
  sampbdate = "",
  sampedate = ""
)

Arguments

df	dataframe with unit value rainfall data
dfQ	dataframe with unit value Q data
date	string Date column in df as POSIXct
Qdate	string Date column in dfQ as POSIXct
rain	string Column in df with instantaneous rain values
Q	string Column in dfQ with instantaneous Q values
df.events	dataframe with start and end dates/times for events
sdate	string Start date column in df.events rain file as POSIXct
edate	string End date column in df.events as POSIXct
erain	string Event rainfall depth column in df.events
plot.buffer	numeric Used to define plotting window in days. Graphs will include
logy	string "y" if log y-axis for Q or "" if linear axis. Will default to "".
site.name	site name as data type character
SampleInfo	if TRUE then sample start and end dates/times are plotted on the hydrograph; if FALSE then sample start and end dates/times are not plotted on the hydrograph.
sampbdate	character column name in df.events for the beginning of the sampling period
sampedate	character column name in df.events for the ending of the sampling period

Value

plots of rainfall events and discharge
