    label,
    fontcolor = "black",
    fontsize = 12,
    rot = 0,
    check.overlap = FALSE,

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.

plot

Input plotgardener plot to internally place text relative to.

x

A numeric vector or unit object specifying text x-location.

y

A numeric vector or unit object specifying text y-location.

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 = "native".

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.
