Description

visVp is supposed to create viewports, which describe rectangular regions on a graphics device and define a number of coordinate systems for each of supra-hexagonal grids.

Usage

visVp(height = 7, xdim = 1, ydim = 1, colNum = 1, rowNum = 1, gp = grid::gpar(), 
  newpage = TRUE)

Arguments

height

a numeric value specifying the height of device

xdim

an integer specifying x-dimension of the grid

ydim

an integer specifying y-dimension of the grid

colNum

an integer specifying the number of columns

rowNum

an integer specifying the number of rows

gp

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

newpage

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

Value

vpnamesan R object of "viewport" class

Note

none

Examples

# 1) create 5x5 viewports
vpnames <- visVp(colNum=5, rowNum=5)

# 2) look at names of these viewports
vpnames
