Source: R/mapview_ext.R
mapview_ext.Rd

A wrapper for mapview::mapview. x can be an sf object or sf list. If nm is NULL and x is an sf list the first item in the list is used.

Usage

mapview_col(x, col = NULL, nm = "data", na.rm = TRUE, ...)

mapview_yn(x, col = NULL, no.rm = TRUE, ...)

mapview_exif(path = NULL, filetype = "jpeg", popup = TRUE, ...)

mapview_flickr(
  x = NULL,
  user_id = NULL,
  tags = NULL,
  api_key = NULL,
  img_size = "s",
  num = 25,
  popup = TRUE,
  ...
)

make_img_leafpop(images, popup = TRUE)

Arguments

x

a Raster* or Spatial* or Satellite or sf or stars object or a list of any combination of those. Furthermore, this can also be a data.frame, a numeric vector or a character string pointing to a tile image folder or file on disk. If missing, a blank map will be drawn. A value of NULL will return NULL.

col

Column name passed to zcol parameter, Default: NULL

nm

Character vector. If x is a sf list, filter the mapview data to those named in nm. If NULL, mapview displays the first item in the sf list; defaults to "data".
