I have an older version of R (2.8.1) and of grid (2.8.1). The source
for grid 2.8.1 does not have pseudonyms.

You're right, I meant to write "lines"not "line". The strange thing
is, although "line" isn't listed in ?unit, it doesn't return an

Reading fromhttp://svn.r-project.org/R/trunk/src/library/grid/src/unit.c
"line" is listed as a pseudonym, so I guess it is a valid unit
after all.

Hi,
I have loaded the [grid] package. It seems that I have to load
another
package?
No. Such a need might have been suggested by a function not found
error. In this case the details are in the help page for the unit
function in grid. The unit parameter was mis-specified.
?unit
Try:
grid.text("t", x=0.3, y=unit(-1, "lines"), vp=vp2)
