A numeric vector or unit object specifying x-location.
y
A numeric vector or unit object specifying y-location.
width
A numeric vector or unit object specifying width.
height
A numeric vector or unit object specifying height.
just
The justification of the clip rectangle
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". For numeric values, 0 means left alignment
and 1 means right alignment.
hjust
A numeric vector specifying horizontal justification.
If specified, overrides the just setting.
vjust
A numeric vector specifying vertical justification.
If specified, overrides the just setting.
default.units
A string indicating the default units to use
if x, y, width, or height
are only given as numeric vectors.
name
A character identifier.
vp
A Grid viewport object (or NULL).
...
Arguments passed to clipGrob.
Details
Both functions create a clip rectangle (a graphical object describing
a clip rectangle), but only grid.clip
enforces the clipping.
Pushing or popping a viewport always overrides the clip
region set by a clip grob, regardless of whether that viewport
explicitly enforces a clipping region.
Value
clipGrob returns a clip grob.

Examples
# draw across entire viewport, but clipped
grid.clip(x = 0.3, width = 0.1)
grid.lines(gp=gpar(col="green", lwd=5))
# draw across entire viewport, but clipped (in different place)
grid.clip(x = 0.7, width = 0.1)
grid.lines(gp=gpar(col="red", lwd=5))
# Viewport sets new clip region
pushViewport(viewport(width=0.5, height=0.5, clip=TRUE))
grid.lines(gp=gpar(col="grey", lwd=3))
# Return to original viewport; get
# clip region from previous grid.clip()
# (NOT from previous viewport clip region)
popViewport()
grid.lines(gp=gpar(col="black"))
