This is a hands-on workshop focused on the high performance aspects of R programming. The attendees would get to learn how to identify the performance issues and address them through the use of various R packages. This workshop is targeted towards audience with a basic familiarity in R.


The following is the outline of the proposed workshop.

1.Understanding R’s slowness
2.Identifying bottlenecks through Profiling
3.Efficient coding practices for improving speed
4.Achieving speed through compiled codes (C++)
5.Overcoming memory limitations
6.Parallel Processing in R

The workshop will include a live demo on each of these topics followed by hands-on lab for the participants.


A basic level of programming familiarity with R.

The technology requirements along with a list of R packages to be installed would be provided a week before the workshop. The R scripts and the datasets would be uploaded to Github and shared with the participants.
