Revert to R 3.2.x code of logicalSubscript in subscript.c?
Currently, in function 'logicalSubscript' in subscript.c, the case of no recycling is handled like the implentation of R function 'which'. It passes through the data only once, but uses more memory. It is since R 3.3.0. For the case of recycling, two passes are done, first to get number of elements in the result.
Also since R...

Intermittent crashes with inset `[<-` command
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.

Suharto,
If you're interested in performance with subscripting, you might want
to look at pqR (pqR-project.org). It has some substantial performance
improvements for subscripting over R Core versions. This is
especially true for the current development version of pqR (probably
leading to a new release in about a month).
You can look at a somewhat-stable snapshot of recent pqR development
