From gtable v0.2.0
by Hadley Wickham
Create a gtable from a matrix of grobs.
Create a gtable from a matrix of grobs.
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.layoutfor 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).
Examples
library(gtable)
library(grid)
a <- rectGrob(gp = gpar(fill = "red"))
b <- circleGrob()
c <- linesGrob()
row <- matrix(list(a, b, c), nrow = 1)
col <- matrix(list(a, b, c), ncol = 1)
mat <- matrix(list(a, b, c, nullGrob()), nrow = 2)
gtable_matrix("demo", row, unit(c(1, 1, 1), "null"), unit(1, "null"))
gtable_matrix("demo", col, unit(1, "null"), unit(c(1, 1, 1), "null"))
gtable_matrix("demo", mat, unit(c(1, 1), "null"), unit(c(1, 1), "null"))
# Can specify z ordering
z <- matrix(c(3, 1, 2, 4), nrow = 2)
gtable_matrix("demo", mat, unit(c(1, 1), "null"), unit(c(1, 1), "null"), z = z)
