coordinates {diagram}R Documentation

coordinates of elements on a plot

Description

estimates coordinates of elements, neatly arranged on a plot

Usage

coordinates(pos=NULL, mx=0.0, my=0.0, N=length(pos), hor=TRUE, 
  relsize=1)

Arguments

pos vector specifying the number of elements in each row, or 2-columned matrix with element position, or NULL
mx horizontal shift (x)
my vertical shift (y)
N total number of elements to be positioned - only if pos=NULL
hor only if pos is a 2-columned matrix. In this case, when hor=TRUE, pos specifies number of elements per row; when FALSE per column (FALSE)
relsize scaling factor as a function of graph size

Details

the position of the elements are specified with "pos", which is either NULL, or a vector specifying the number of elements on a row, or a 2-columned matrix specifying the (x,y) position of each element.

The offset from the x-axis and from the y-axis can be changed with mx and my

Value

2-columned matrix, with coordinates (x,y) of each of the elements
