[Rd] beginner finds a bug - crash induced. (PR#8035)
Well,
you say yourself it wasn't reproducible. So it could have been
anything that "crashed" you R , cosmic radiation, a bolt of
lightning reversing a bit in your computer memory ,... :-)
many things rather than a bug in R.
But before dropping this report completely,
can you try
for(i in 1:1000) {
state <- c("tas", "sa", "qld",
"nsw", "nsw", "nt", "wa",
"wa",
"qld", "vic", "nsw",
"vic", "qld", "qld", "sa",
"tas",
"sa", "nt", "wa",
"vic", "qld", "nsw", "nsw",
"wa",
"sa", "act", "nsw",
"vic", "vic", "act")
print(factor(state))
