Description

Wrapper function for plotting identified events.

Usage

plotEvents(
  data,
  dates = NULL,
  events,
  type = "lineover",
  colline = "red",
  colpnt = "blue",
  colbound = "red",
  ymin = min(data),
  ymax = max(data),
  xlab = "",
  ylab = "",
  main = "events"
)

Arguments

data	The data vector
dates	Optional date vector
events	Events data frame
type	The type of plot (see details)
colline	Line colour
colpnt	Point colour
colbound	Background colour for plot type "bound"
ymin	Minimum plot extend in vertical direction
ymax	Maximum plot extent in vertical direction
xlab	x-axis label
ylab	y-axis label
main	Plot title

Examples

# Plot events
library(hydroEvents)
BFI_res = eventBaseflow(dataBassRiver)

oldpar <- par(mfrow = c(3, 1), mar = c(3, 2.7, 2, 1))
d = as.Date("1974-06-30") + 0:(length(dataBassRiver)-1)
plotEvents(data = dataBassRiver, dates = d, events = BFI_res,
   type = "lineover", xlab = "Date", ylab = "Flow (ML/day)", main = "lineover")
plotEvents(data = dataBassRiver, dates = d, events = BFI_res, type = "bound",
   xlab = "Date", ylab = "Flow (ML/day)", main = "bound")
plotEvents(data = dataBassRiver, dates = d, events = BFI_res, type = "hyet",
   xlab = "Date", ylab = "Flow (ML/day)", main = "hyet")
par(oldpar)
