Arguments

sMap

an object of class "sMap"

sBase

an object of class "sBase"

height

a numeric value specifying the height of device

margin

margins as units of length 4 or 1

area.size

an inteter or a vector specifying the area size of each hexagon

gp

an object of class "gpar". It is the output from a call to the function "gpar" (i.e., a list of graphical parameter settings)

border.color

the border color for each hexagon

fill.color

the filled color for each hexagon

lty

the line type for each hexagon. 0 for 'blank', 1 for 'solid', 2 for 'dashed', 3 for 'dotted', 4 for 'dotdash', 5 for 'longdash', 6 for 'twodash'

lwd

the line width for each hexagon

lineend

the line end style for each hexagon. It can be one of 'round', 'butt' and 'square'

linejoin

the line join style for each hexagon. It can be one of 'round', 'mitre' and 'bevel'

colormap

short name for the colormap. It can be one of "jet" (jet colormap), "bwr" (blue-white-red colormap), "gbr" (green-black-red colormap), "wyr" (white-yellow-red colormap), "br" (black-red colormap), "yr" (yellow-red colormap), "wb" (white-black colormap), and "rainbow" (rainbow colormap, that is, red-yellow-green-cyan-blue-magenta). Alternatively, any hyphen-separated HTML color names, e.g. "blue-black-yellow", "royalblue-white-sandybrown", "darkgreen-white-darkviolet". A list of standard color names can be found in http://html-color-codes.info/color-names

clip

either "on" for clipping to the extent of this viewport, "inherit" for inheriting the clipping region from the parent viewport, or "off" to turn clipping off altogether

newpage

logical to indicate whether to open a new page. By default, it sets to true for opening a new page

Value

invisible

Note

none
