View source: R/points2nearestcell.R

Move point occurrences falling in raster cells without data (i.e. NA) to the nearest raster cell with data.

points2nearestcell(
  locs = NULL,
  ras = NULL,
  layer = 1,
  move = TRUE,
  distance = NULL,
  showchanges = TRUE,
  showmap = TRUE,
  leaflet = FALSE
)

`locs`	A SpatialPoints or SpatialPointsDataFrame.
`ras`	`Raster*` object.
`layer`	Integer. For RasterStack and RasterBrick objects, layer to use.
`move`	Logical. Change coordinates of points to those of the nearest raster cells?
`distance`	Numeric (optional). Maximum distance to move points. Point coordinates are only changed if the distance to the nearest raster cell is below `distance`.
`showchanges`	Logical. Print table with old and new coordinates.
`showmap`	Logical. Show map with original and new coordinates?
`leaflet`	Logical. If TRUE, show leaflet map instead of static map.

A SpatialPointsDataFrame (with corrected coordinates if move is TRUE).
