Questions
If there is an error with conditions or code in Rstudio, to fix the error do we need to run all the code again like how Python does?
- Alt + Ctrl + P: run everything up to current line
Start with the first error, then move to next one
“One-way street”: to work cleanly, and check that everything works, start a new session and run the whole script from top to bottom
Efficiency with large tables?
polars in python
Try using purrr in the tidyverse, or data.table, or search for “sparse matrix”
profiling: integrated in RStudio: select code > Profile menu > Profile Selected Lines
