![[Superseded]](figures/lifecycle-superseded.svg)
sample_n() and sample_frac() have been superseded in favour of
slice_sample(). While they will not be deprecated in the near future,
retirement means that we will only perform critical bug fixes, so we recommend
moving to the newer alternative.
These functions were superseded because we realised it was more convenient to
have two mutually exclusive arguments to one function, rather than two
separate functions. This also made it to clean up a few other smaller
design issues with sample_n()/sample_frac:
The connection to
slice()was not obvious.The name of the first argument,
tbl, is inconsistent with other single table verbs which use.data.The
sizeargument uses tidy evaluation, which is surprising and undocumented.It was easier to remove the deprecated
.envargument....was in a suboptimal position.
sample_n(tbl, size, replace = FALSE, weight = NULL, .env = NULL, ...) sample_frac(tbl, size = 1, replace = FALSE, weight = NULL, .env = NULL, ...)
Arguments
| tbl | A data.frame. |
|---|---|
| size | < |
| replace | Sample with or without replacement? |
| weight | < |
| .env | DEPRECATED. |
| ... | ignored |
