Making legend grobs

Legend(at, labels = at, nrow = NULL, ncol = 1, col_fun,
    grid_height = unit(4, "mm"), grid_width = unit(4, "mm"), gap = unit(2, "mm"),
    labels_gp = gpar(fontsize = 10),
    border = NULL, background = "#EEEEEE",
    type = "grid", legend_gp = gpar(),
    pch = 16, size = unit(2, "mm"),
    legend_height = NULL, legend_width = NULL,
    direction = c("vertical", "horizontal"),
    title = "", title_gp = gpar(fontsize = 10, fontface = "bold"),
    title_position = c("topleft", "topcenter", "leftcenter", "lefttop"))

`at`	breaks, can be wither numeric or character
`labels`	labels corresponding to `at`
`nrow`	if there are too many legends, they can be positioned in an array, this controls number of rows
`ncol`	if there are too many legends, they can be positioned in an array, this controls number of columns. At a same time only one of `nrow` and `ncol` can be specified.
`col_fun`	a color mapping function which is used to make a continuous color bar
`grid_height`	height of legend grid
`grid_width`	width of legend grid
`gap`	when legends are put in multiple columns, this is the gap between neighbouring columns, measured as a `unit` object
`labels_gp`	graphic parameters for labels
`border`	color of legend borders, also for the ticks in the continuous legend
`background`	background colors
`type`	type of legends, can be `grid`, `points` and `lines`
`legend_gp`	graphic parameters for the legend
`pch`	type of points
`size`	size of points
`legend_height`	height of the whole legend, used when `col_fun` is specified and `direction` is set to `vertical`
`legend_width`	width of the whole legend, used when `col_fun` is specified and `direction` is set to `horizontal`
`direction`	direction of the continuous legend
`title`	title of the legend
`title_gp`	graphic parameters of title
`title_position`	position of title according to the legend
