Tools at the intersection of purrr and dplyr
License: GNU General Public License v3.0
purrrlyr contains some functions that lie at the intersection of purrr and dplyr. They have been removed from purrr in order to make the package lighter and because they have been replaced by other solutions in the tidyverse.
Please see Jenny Brian's webinar on row-oriented workflows for some alternative approaches.

mutate(Date = as.Date(paste0(year, "-", month, "-", day))) %>%
by_row(function(.d) {select(.d, Date)}, .to = "new", .collate = "rows")

If I understand correctly, these are essentially functions that have been deprecated from tidyverse and have better alternatives?
because they have been replaced by other solutions in the tidyverse.
I think it would help folks migrate more easily to the preferred syntax if this package included a quick example of how the same thing is accomplished with tidyverse functions, or at least a quick pointer to the preferred patterns.
(e.g. I'm still trying to wrap my own head around the best way to iterate an arbitrary function through the rows of a data.frame, a la dplyr::rowwise+dplyr::do, purrrlyr::by_rows, tidyr::nest etc. I'm guessing nest is the preferred pattern these days)
For the by_* functions, any factor columns in a data frame returned by the function to be applied get converted to ints when collating by rows:
