The patch()
function is used by wrap()
and inset()
to convert objects
into a grob.
# S3 method for trellis
patch(x, ..., device = NULL)
A grob object.
An object to be converted into a grob.
Arguments passed on to grid::grid.grabExpr
warn
An integer specifying the amount of warnings to emit. 0 means no warnings, 1 means warn when it is certain that the grab will not faithfully represent the original scene. 2 means warn if there's any possibility that the grab will not faithfully represent the original scene.
wrap
A logical indicating how the output should
be captured. If TRUE
, each non-grob element on the
display list is captured by wrapping it in a grob.
wrap.grobs
A logical indicating whether, if we are wrapping
elements (wrap=TRUE
), we should wrap grobs (or just
wrap viewports).
width,height
Size of the device used for temporary rendering.
A function that opens a graphics device for temporary
rendering. By default this is an off-screen, in-memory device
based on the pdf
device, but this default device may not be
satisfactory when using custom fonts.
