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)
--
grid.text("s", 0.8, unit(-1, "lines"), gp=gpar(col="red"), vp=vp2)
