gtable (version 0.1.1)

gtable_matrix: Create a gtable from a matrix of grobs.

Description

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

z

a numeric matrix of the same dimensions as grobs, specifying the order that the grobs are drawn.

vp

a grid viewport object (or NULL).

name

a string giving the name of the table. This is used to name the layout viewport

widths

a unit vector giving the width of each column

heights

a unit vector giving the height of each row

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

grobs

a single grob or a list of grobs

clip

should drawing be clipped to the specified cells ("on"), the entire table ("inherit"), or not at all ("off")

Examples

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)
