plotEvents function

Plot Events

Wrapper function for plotting identified events.

plotEvents(
  data,
  dates = NULL,
  events,
  type = "lineover",
  colline = "red",
  colpnt = "blue",
  colbound = "red",
  ymin = min(data),
  ymax = max(data),
  xmin = NULL,
  xmax = NULL,
  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 extent in vertical direction
• ymax: Maximum plot extent in vertical direction
• xmin: Minimum plot extent in horizontal direction
• xmax: Maximum plot extent in horizontal direction
• xlab: x-axis label
• ylab: y-axis label
• main: Plot title

Returns

No return value.

Details

Three plot types are implemented: "lineover", "bound", "hyet". See examples. If events contains a column titled "which.max" the maxima are also plotted.

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)
