Transform a layout matrix into a position one
This function transforms layout's informations into a position matrix useful for
ADEgS and for lattice graphics.
layout2position(mat, widths = rep(1, NCOL(mat)), heights = rep(1, NROW(mat)), ng, square = FALSE)
mat |
a matrix indicating the location of figures to display (each value must be 0 or a positive integer) or a two-length vector indicating the number of rows and columns in the corresponding layout. |
widths |
a vector of relative values for the columns' widths on the device. Their sum must be equal to the number of columns. |
heights |
a vector of relative values for the rows' heights on the device. Their sum must be equal to the number of rows. |
ng |
a value for the number of positions needed (i.e. the number of graphics to plot) |
square |
a logical indicating if the graphics is an isometric plot |
A four-columns matrix indicating the coordinates (in normalized parent coordinates npc)
of the top-right and bottom-left hand corners of each displayed figure on the device.
This function is strongly inspired by the layout function in graphics package.
