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 )
db | Data frame. Cell by cell data on the elevation of the watershed.
Output by LITAP's |
---|---|
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 |
