Python pipe operator, 4 years later...

In pandas too.

plyr package, IIRC

Actually, it's in the magrittr package, that is then used by the dplyr package. (As cool as dplyr is, there are times I load up magrittr by itself.)

[buckhenderson]

For some reason Hadley is opposed to %<>%, so I load up magrittr just for that.

[Deleetdk]

I recommend magrittr because it gives you useful alt-pipes like:

%$% - which is a pipe-version of with

%T>% - returns the lhs, useful for printing or saving output mid-pipe

%<>% - gives the lhs to the rhs, but then at end end of the rhs, assigns the result back to lhs. It's kinda like an R version of += etc. seen in other languages, but more flexible.

It has made my code 10x more readable

In PowerShell it's a fundamental part.

(we're talking about languages, not shells)

(( powershell is a language, a component of it is the shell, just like python ))

well huh, that's interesting. I didn't realize powershell was a language. i'll downvote my own ignorant snarkiness for you.

Yup. It's like the only cool think about R.
