With the advent of a more cohesive and complete dtplyr
, I’ve been
wanting to write about how it can be used with tidyfast
to use the
syntax of the tidyverse
while relying on the speed and efficiency of
data.table
. This workflow is already being adopted by some, including
Ivan
Leung,

This post highlights six major themes of what I learned while creating the
tidyfast
R package. This process
taught me about the tidyverse
, data.table
, R
, and data science in
general.

As I’ve spent time learning about different approaches to working with
data, I’ve seen several subtle, but important, differences in how to do
things. This very short post is presenting how one can perform
vectorized “if else” functions in R
. The idea of “if else” basically is:

This short post is looking at data joins for both dplyr
and data.table
. There are a lot of moving parts when assessing these things, so the results here are just for this situation. It may differ in others. However, the results here are quite instructive.

As of late, I have used the data.table
package to do some of my data
wrangling. It has been a fun adventure (the nerd type of fun). This was
made more meaningful with the renewed development of the dtplyr
package by Hadley Wickham and co. I introduce some of the different
behavior of data.table
here.
