Create plots of water flow — flow

Plots water flow and watersheds. See the flow_plot article/vignette for examples.

flow_plot(
  db,
  type = "relief",
  dir = FALSE,
  seqno = FALSE,
  highlight = FALSE,
  shed = FALSE,
  shed_type = "local",
  pits = FALSE,
  upslope_threshold = NULL,
  cells = NULL,
  clim = NULL,
  rlim = NULL,
  stats = NULL,
  missing = NA
)

Arguments

db: Data frame. Cell by cell data on the elevation of the watershed. Output by LITAP's flow_mapper() function.
type: Character. Either relief or elevation. Defaults to relief.
dir: Logical. Include flow directions?
seqno: Logical. Include cell numbering?
highlight: Logical. Highlight selected cells?
shed: Logical. Show watersheds?
shed_type: Character. Which type of watershed, must be included as a column in the data frame. Can be one of 'initial', 'local', 'fill', 'inv_initial', or 'inv_local'/'inverted'.
pits: Logical. Show watershed pits (lowest point)
upslope_threshold: Numeric. If dir = TRUE, only show flow directions for cells with >= this many cells which drain to it.
cells: Vector. Which cells to show
clim: Numeric vector. Column limits in format c(0, 100)
rlim: Numeric vector. Row limits in format c(0, 100)
stats: Data frame. Data frame of watershed stats to highlight pour points.
missing: Character. What is the value of missing data? Defaults to NA
