Full_Name: John Brzustowski Version: R-devel-trunk, R-2.4.0 OS: linux, gcc 4.0.3 Submission from: (NULL) (206.248.157.184) This isn't a bug, but an easily-remedied performance issue. SYMPTOM > for (i in 1000 * (1:20)) { y <- paste(rep("asdf", times=i), collapse=" ") t <- system.time(...

Full_Name: John Brzustowski Version: R-devel-trunk OS: linux (problem under Windows too) Submission from: (NULL) (74.101.124.238) (This bug was discovered by Phil Taylor, Acadia University.) I'm not sure from reading the documentation whether strptime(x, "%j") is meant to be supported, but if so, there is a bu...

Full_Name: John Brzustowski Version: R-devel-trunk, R-2.4.0 OS: linux Submission from: (NULL) (206.248.132.197) DESCRIPTION seek() on files larger than 2 gigabytes fails for large values of "where" on i386 linux 2.6.13 (and presumably other 32-bit unix-like platforms). e.g.: > f<-file("3gigabytefile....

Full_Name: John Brzustowski Version: R-devel trunk and R-2.4.0 OS: linux Submission from: (NULL) (76.10.152.79) Here are two minor potential issues in pointer protection stack (PPS) code which could arise in debugging R with valgrind. Only the second could possibly cause a problem in normal use of R, and only under laughab...

Full_Name: John Brzustowski Version: 2.8.1 OS: linux Submission from: (NULL) (67.71.250.146) When entering a debug()'ed function, the call printout is not limited by options()$deparse.max.lines as it is when one uses browser() or trace(). Should it be? If so, here's a patch: diff -cr R-2.8.1/src/library/base/man/...

This is really due to two minor bugs, but because they interact, I'm submitting this as one report.
