Is this a bug?
Yes. If you look inside the saved file it contains
..., call = dist(x = USArrests), ...
When this is reread, an attempt is made to evaluate the call. Some kind of quoting is needed.
I do this:
library(mva) data(USArrests) d <- dist(USArrests) dump("d", "tst") q()
I restart R and do this:
source("tst")
And I get:
Error in as.matrix(x) : Object "USArrests" not found
