Plot text within a plotgardener layout

Description

Plot text within a plotgardener layout

Usage

plotText(
    label,
    fontcolor = "black",
    fontsize = 12,
    rot = 0,
    check.overlap = FALSE,
    x,
    y,
    just = "center",
    default.units = "inches",
    params = NULL,
    ...
)

Arguments

label	Character or expression of text to be plotted.
fontcolor	A character value specifying text fontcolor. Default value is fontcolor = "black".
fontsize	A numeric specifying text fontsize in points. Default value is fontsize = 12.
rot	A numeric specifying the angle to rotate the text. Default value is rot = 0.
check.overlap	A logical value to indicate whether to check for and omit overlapping text. Default value is check.overlap = FALSE.
x	A numeric vector or unit object specifying text x-location.
y	A numeric vector, unit object, or a character vector of values containing a "b" combined with a numeric value specifying text y-locations. The character vector will place text y-locations relative to the bottom of the most recently plotted plot according to the units of the plotgardener page.
just	Justification of text relative to its (x, y) location. If there are two values, the first value specifies horizontal justification and the second value specifies vertical justification. Possible string values are: "left", "right", "centre", "center", "bottom", and "top". Default value is just = "center".
default.units	A string indicating the default units to use if x or y are only given as numerics or numeric vectors. Default value is default.units = "inches".
params	An optional pgParams object containing relevant function parameters.
...	Additional grid graphical parameters. See gpar.

Value

Returns a text object containing relevant placement and grob information.
