Cytometry in R - Week #4 - Introduction to Tidyverse

[UMGCCCFCSR]

Hello All,

Course materials for "Cytometry in R - Week # 4 - Introduction to Tidyverse" are now available via the course website and GitHub repository. For previous course emails, see here .

The tidyverse is a collection of R packages that have collectively over the last 15 years made R much easier to use. They are premised on the concept of "tidy data", (thinking of/organizing everything as rows and columns in a table) which are summarized in this paper. This week, we will learn about the main tidyverse functions we will be using throughout the course, and how to apply them to our own datasets to make analysis simpler, as well as more replicable and reproducible in the long run.

If you have fallen behind or have not yet started the course, please let me reasure you that there is absolutely nothing wrong with that. Life always has a way of getting in the way, and some material can be harder to fully grasp and absorb when first encountered. In the end, your goal is to learn and apply the material, not to exactly match the pace of a course that jumps to a new topic each week. Fortunately, the best thing about our format is that the recordings and course materials will always be available for when you have time. We will continue to monitor the Discussion Forum for questions related to all weeks.

If you submitted the optional take-home problems and encountered an issue syncing and pulling in new changes to the course Cytometry in R folder, please refer to this walkthrough for steps on how to resolve (please back up your homework folders first!). Starting this week, we will modify the pull request procedure by having you create a branch, and carry out a branch-to-branch pull request, see here for details. This should hopefully resolve the issue going forward.

For those in Baltimore attending (or wanting to attend ) in-person, the only in-person session this week is Thursday at 4 PM EST (Bressler Research Building 7-035). due to low attendance other two days. If you have a strong preference for the other days being reinstated, please let us know. As a reminder, this is a volunteer-led initiative, on our own time after hours, aimed at providing resources to the community. We try to balance what is being covered based on what all those who are present need, so compromises are made and not all weekly material may be covered.

For those joining online, the YouTube livestreams (each covering the same material) are offered on

• Tuesday 2200 EST (Wednesday 0300 GMT+0),
• Wednesday 1600 EST (Wednesday 2100 GMT+0)
• Thursday 1000 EST (Thursday 1500 GMT+0)

Recordings are available immediately after.

And for anyone who might be interest, the FlowTex conference is being livestreamed this week on YouTube and is always worth checking out 😃 (All times are CST (GMT-6))

Best Wishes-
David
