It's been a while since I looked at it but I am fairly certain that `caret` and/or `mlr3` already cover it for #rstats.
It is a not uncommon task. Here is a tweet from just yesterday doing it for #rspatial data too:
New version of #rstats #rspatial package CAST allows visualizing whether training data for #MachineLearning have representative coverage of the prediction area and whether CV folds are appropriately chosen. Tutorial: hannameyer.github.io/CAST/ar…

Hey, look, round number at CRAN!
A big, big thank you to the CRAN maintainers who are volunteers putting together an unparallel repository with unmatched quality guarantees, year in and out. Very much appreciated!
(Even if #RStats package authors like myself grumble at times.)

My name is Dirk, and I endorse this package.
As I did a year ago in a talk at the @Bioconductor developer forum; video at youtube.com/watch?v=nmY1jIhY… and slides at dirk.eddelbuettel.com/papers… #rstats
#rstats package tinytest now used to unit-test 200+ packages on CRAN! Thanks to all users for your trust in the package, and for all your valuable suggestions!

The second (and more advanced, covering 'live' (financial) market monitoring via pub/sub) of the two new vignettes in package `RcppRedis` is now also on arXiv at, respectively, arxiv.org/abs/2203.08323, and doi.org/10.48550/arXiv.2203.…. #rcpp #rstats

S, of course.
Which dates back to May 5, 1976, at Bell Labs and what followed. You may find the excellent article on "S, #RStats, and Data Science" by John Chambers in the ACM HOPL issue interesting if all this new to you:

If you're getting sliced and diced by the bleeding edge, #rocker to the rescue with a container for #rstats with gcc-12. Thanks to @eddelbuettel.
New linter in gcc-12 identified a real problem in my code (first picked up by CRAN, verified with r-edge).

The first (and more introductory) of the two new vignettes in package `RcppRedis` is now on arXiv at, respectively, arxiv.org/abs/2203.06559 and doi.org/10.48550/arXiv.2203.…. #rcpp #rstats

It's a NOTE.
Not a WARNING or ERROR. There a lots of packages with larger installed footprints.
So you can proceed. But you can consider it as hint to maybe reduce same sample data or documentation.

With daughter #1 in town for her first big grad school conference (hello to the APS meeting at McCormick Place) I fired up a family favourite recipe @bittman's HTCE: crispy pork with orange and black beans.

An underappreciated #rstats simulation option is simple mixtures: eg 80% from N(0,1) and 20% from N(0,5) giving fatter tails "cheaply":
> set.seed(42)
> X <- c(rnorm(10000,0,1), rnorm(2500,0,5))
> e1071::skewness(X)
[1] -0.00247981
> e1071::kurtosis(X)
[1] 7.92564

The quote below is from the @duckdb documentation, but holds in general: don't use `insert` for bulk operations.
Rather look at the _specific_ documentation for _your_ SQL backend and see what it recommends for bulk.
Or else just be very patient.

dtts 0.1.0 on CRAN: New Package
data.table time series ops at nanosecond resolution

#rstats #rcpp
Think `xts` but at nanosecond resolution. All the immense power of `data.table` at the hightest time resolution.

The @Debian package for #RStats 4.1.3 released today was updated a few hours ago, used to update the #RockerProject container, and PRed as usual into @Docker itself to update the official r-base container. @marutterstat will follow-up as usual with @Ubuntu binaries.
#rstats 4.1.3 "One Push-Up" (source version) has been released. Binaries will follow in due course.
