coordinates {diagram} | R Documentation |
estimates coordinates of elements, neatly arranged on a plot
coordinates(pos=NULL, mx=0.0, my=0.0, N=length(pos), hor=TRUE, relsize=1)
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 |
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
2-columned matrix, with coordinates (x,y) of each of the elements
