I will add a "[.tile.list" method in the next release of deldir so that
the appropriate attributes are preserved. This won't happen for a month
or so though; I have some other pressures on me at the moment.
cheers,

Thanks Boris!
I know that I am just leaving out some tiles in the plot, but I
specifically want to drop those tiles for the plot and not calculate a
tesselation without these points. So I'll go with this solution and
hope it makes sense in the end.
Thanks again!

plot.tile.list() expects its argument to be of class tile.list, and to have
an attribute "rw", both of which are not conserved after subsetting. You can
do ...
if (!require(deldir)) {
install.packages("deldir")
library(deldir)
}
x <- rnorm(10)
y <- rnorm(10)
del <- deldir(x, y)
tl <- tile.list(del)
tl2 <- tl[1:4]
class(tl2) <- "tile.list"
attr(tl2, "rw") <- attr(tl, "rw")
plot.tile.list(tl2) # or just plot(tl2)
BUT!
This doesn't really make sense because you are just "randomly" plotting some
tiles from the full triangulation, not plotting a triangulation with less
points. That would be:
plot(tile.list(deldir(x[1:4], y[1:4])))
