...rs to be related to long vector support. But as Henrik Bengtsson points out at https://github.com/HenrikBengtsson/Wishlist-for-R/issues/97#issuecomment-562659134, writeBin() still prohibits long vectors. Are there any plans to add long vector support to R 4.0.0? x <- raw(2^31) writeBin(x, con = nullfile()) # Error in writeBin(x, con = nullfile()) : # long vectors not supported yet: connections.c:4430 x <- raw(2^31) con <- rawConnection(raw(0L), "w") writeBin(raw(2^31), con = con) # Error in writeBin(raw(2^31), con = con) : # long vectors not supported yet: connections.c:4430...

A relatively simple way to hang an R session for a long-ish time would therefore be: f <- xzfile(nullfile(), 'a+b') x <- rep(0, 1e9) # approx. 8 gigabytes, adjust for your RAM size serialize(x, f) close(f) This means that calling R_CheckUserInterrupt() between saving individual objects is not enough: R also needs to check for interrupts while saving sufficiently long vectors. Since the se...

Hello, Could save.image() be redesigned so that it promptly responds to Ctrl+C? It prevents the command line from being used for a number of hours if the contents of the workspace are large. -------------------------------------- Dario Strbenac University of Sydney Camperdown NSW 2050 Australia
