gtable_matrix
Create a gtable from a matrix of grobs.
This function takes a matrix of grobs and create a gtable matching with the grobs in the same position as they were in the matrix, with the given heights and widths.
Usage
gtable_matrix(name, grobs, widths = NULL, heights = NULL, z = NULL,
respect = FALSE, clip = "on", vp = NULL)Arguments
- 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
grobs, specifying the order that the grobs are drawn.- respect
a logical vector of length 1: should the aspect ratio of height and width specified in null units be respected. See
grid.layout()for more details- clip
should drawing be clipped to the specified cells (
"on"), the entire table ("inherit"), or not at all ("off")- vp
a grid viewport object (or NULL).
Value
A gtable of the same dimensions as the grobs matrix.
