QUESTION
I'm getting some very weird behavior from mixing tidyverse
and data.table
syntax.
For context, I often find myself using tidyverse
syntax, and then adding a pipe back to data.table
when I need speed vs. when I need code readability. I know Hadley's working on a new package that uses tidyverse
syntax with data.table
speed, but from what I see, it's still in it's nascent phases, so I haven't been using it.
Anyone care to explain what's going on here? This is very scary for me, as I've probably done these thousands of times without thinking.

Answered 2021-Jun-15 at 06:35I came across the same problem on a few occasions, which led me to avoid mixing dplyr
with data.table
syntax, as I didn't take the time to find out the reason. So thanks for providing a MRE.
Looks like dplyr::arrange
is interfering with data.table
auto-indexing :
- index will be used when subsetting dataset with
==
or%in%
on a single variable- by default if index for a variable is not present on filtering, it is automatically created and used
- indexes are lost if you change the order of data
- you can check if you are using index with
options(datatable.verbose=TRUE)
If we explicitely set auto-indexing :
QUESTION
My end goal is to create islands of continuous enrollment days for each CLIENTID
for a single sub-population: 'Adult Expansion' for calendar years 2019 and 2020. A CLIENTID
can be associated with multiple sub-populations in a calendar year, but can never be associated with more than one sub-population at once (there is no overlap in enrollment). My data go back to 2016, but I am only interested in 2019 and 2020. The data are structured that each row is a single enrollment period, with start and end dates of enrollment, associated with a sub-population.
I've included below some dummy data and a desired output to better illustrate my goal:
