object of class
further arguments: for
plot, passed on to
image, passed on to
TRUE, compute a single, joint zlim (color scale) for all subplots from
character; subplot title prefix; use
"" to get only time, use
NULL to suppress subplot titles
logical; should axes and box be added to the plot?
logical or numeric; if
TRUE will try to plot not many more pixels than actually are visible, if
FALSE, no downsampling takes place, if numeric, the number of pixels/lines/bands etc that will be skipped; see Details.
number of color breaks; should be one more than number of colors. If missing and
col is specified, it is derived from that.
actual color breaks, or a method name used for classIntervals.
colors to use for grid cells
integer; side to plot a color key: 1 bottom, 2 left, 3 top, 4 right; set to
NULL to omit key. Ignored if multiple columns are plotted in a single function call. Default depends on plot size, map aspect, and, if set, parameter
amount of space reserved for width of the key (labels); relative or absolute (using lcm)
amount of space reserved for length of the key (labels); relative or absolute (using lcm)
FALSE, keep the plot in a mode that allows adding further map elements; if
TRUE restore original mode after plotting
color for box around sub-plots; use
0 to suppress plotting of boxes around sub-plots.
TRUE, sub-plot titles will show the center of time intervals, otherwise their start
NULL or function; hook function that will be called on every sub-plot.
length-2 integer vector with nrows, ncolumns of a composite plot, to override the default layout
integer; which band (dimension) to plot
integer; which attribute to plot
numeric; aspect ratio of image
integer; specify three bands to form an rgb composite. Experimental: rgb color table; see Details.
numeric; passed on to rgb
character; x axis label
character; y axis label
x axis limits
y axis limits
logical; print values as text on image?
character; color for printed text values
logical; when using rasterImage (rgb), should pixels be interpolated?
logical; for curvilinear or sheared grids: parameter passed on to st_as_sf, determining whether raster cells will be plotted as symbols (fast, approximate) or small polygons (slow, exact)
TRUE, use log10-scale for the attribute variable. In that case,
at need to be given as log10-values; see examples.
object of class
sfc, or list with arguments to
plot, that will be added to an image or sub-image
color used for cell borders (only in case
x is a curvilinear or rotated/sheared grid)
logical; use the rasterImage capabilities of the graphics device?
object which has a
st_bbox method; sets the plotting extent
Downsampling: a value for
downsample of 0: no downsampling, 1: after every dimension value (pixel/line/band), one value is skipped (half of the original resolution), 2: after every dimension value, 2 values are skipped (one third of the original resolution), etc.
use of an rgb color table is experimental; see https://github.com/r-spatial/mapview/issues/208
when plotting a subsetted
stars_proxy object, the default value for argument
downsample will not be computed correctly, and has to be set manually.
