I suggest either adding a short code piece to use the rename() function to change the column "genus" to "genera" (thus alerting the learners to their relationship here, while adding a new function) or changing the column name in the original dataset. Otherwise, I've found that using the correct plural for genus confuses learners who are not biologists. Although it's the R ecology lesson and one

In episode 3 (https://datacarpentry.org/python-ecology-lesson/03-index-slice-subset/index.html, actually listed as 4. in https://datacarpentry.org/python-ecology-lesson/ ), the distinction between .iloc method for accessing entries by position and .loc to access them by identifier is made, but a third possibility is shown with surveys_df[0:3], which accesses the indices by position.

That

A small thing, and not very important, but it seems redundant to end every episodes title with "in R" since the name of the lesson is "Introduction to Geospatial Raster and Vector Data with R" and all the episodes use R. Furthermore, there are three episodes that don't say "in R" that do in fact use R....

Have you taught this lesson? One way you can help us improve it is by filing issues here about typos you've discovered, but you can also help us fill out the instructor notes!

What is SQL
SQL stands for Structured Query Language. SQL allows us to interact with relational databases through queries. These queries can allow you to perform a number of actions such as: insert, update and delete information in a database.

can we edit it to the following

In previous experience teaching dplyr I have found that using Hadley Wickham's split-apply-combine language has helped students understand the power of dplyr, and might make some of the later exercises (and diagrams) easier to understand.

It would be very useful to create a template for the schedule of a geospatial workshop to be used in the workshop website. This schedule should be added to this file: https://github.com/carpentries/workshop-template/blob/gh-pages/_includes/dc/schedule.html

egen help does not list sum as a valid function, it is total instead. We should update the examples.

sum works, but is deprecated

It is probably worth pre-emptively answering, in the Introduction, a question researchers often ask ... Is my data safe or is it being copied or uploaded? This is almost answered (indirectly) in the "Before we get started" section, but I'd highlight it as a "Feature".

This will remind novice users to be aware of where their data is going (which can be confusing in these days of xAAS), while re
