The following code crashes after about 300 iterations on
my?x86_64-w64-mingw32?machine on R 3.5.2 --vanilla.??
Others have duplicated this
(see?https://github.com/tidyverse/magrittr/issues/190?if necessary), but I
don't know how machine/OS-dependent it may be.??
If it doesn't crash for you, please try increasing the length of the x
vector.
Substituting the commented-out line for the one below it works correctly (prints
out 1:1000 and ends normally) every time.
x <- 1:200000
y <- rep(letters[1:5], length(x) / 5L)
for (i in 1:1000) {
? # x[y == 'a'] <- x[y == 'b']
? x <- `[<-`(x, y == 'a', x[y == 'b'])
? cat(i, '')
}
cat('\n')
The point of using this syntax is to make it work better with pipes, but the
errors occur without pipes or magrittr.
Thank you for your help!
Hi Brian, I don't have a windows machine, but on a modern macbook pro I'm not able to get this to crash in 3.5.1 or a very recent built-from-source R-devel. I increased the length of x by 2 orders of magnitude but that just made the loop take a lot longer to successfully run in both R versions i tested. So seems like there is some OS/machine dependency at work here (?).

Hello, I can also reproduce this, R 3.5.2 on Ubuntu 18.04 LTS. First run gives error after 148. After 148: Error in `[<-`(x, y == "a", x[y == "b"]) : substituto tem comprimento zero Execu??o interrompida Translation: replacement has length zero Execution stopped Second run gives a different error, I changed the script to start with a sessionInfo() instruction, everything else is the same as in the OP. After 180: *** caught segfault *** address 0x700000002, cause 'memory not mapped' An irrecoverable exception occurred. R is aborting now ... Several runs with or without the sessionInfo() always give the two different errors above.
