gtable_matrix {gtable} | R Documentation |
Create a gtable from a matrix of grobs.
gtable_matrix(name, grobs, widths = NULL, heights = NULL, z = NULL, respect = FALSE, clip = "on", vp = NULL)
name |
a string giving the name of the table. This is used to name the layout viewport |
grobs |
a single grob or a list of grobs |
widths |
a unit vector giving the width of each column |
heights |
a unit vector giving the height of each row |
z |
a numeric matrix of the same dimensions as |
respect |
a logical vector of length 1: should the aspect ratio of
height and width specified in null units be respected. See
|
clip |
should drawing be clipped to the specified cells
( |
vp |
a grid viewport object (or NULL). |
