Dear useRs, When the implementation of the native pipe was announced (e.g. https://www.r-bloggers.com/2021/05/the-new-r-pipe/), there was no placeholder similar to the dot in magrittr. Has it changed? Is there now a placeholder? There is no mention of it in the help page for "|>" so I guess not, but maybe someone on the list knows more about future developments? Thank you!

Not currently, but you can emulate it with the anonymous function shorthand: (\(.) expression_using_dot ))() e.g. https://i.reddit.com/r/rstats/comments/nkiavh/is_base_r_pipe_faster_than_dplyr/ On March 9, 2022 4:57:36 AM PST, Ivan Calandra <ivan.calandra at rgzm.de> wrote:>Dear useRs, > >When the implementation of the native pipe was announced (e.g. >https://www.r-bloggers.com/2021/05/the-new-r-pipe/), there was no >placeholder similar to the dot in magrittr. > >Has it changed?
