R for Reproducible Scientific Analysis
The [list subsetting exercise](https://swcarpentry.github.io/r-novice-gapminder/06-data-subsetting.html#list-subsetting) references the built-in dataset `mtcars`. Consider including an explanation of what that is and why we did not need to define it as we did all...
[Between challenges 8 and 9 in this lesson](https://swcarpentry.github.io/r-novice-gapminder/04-data-structures-part1.html#challenge-8), there is a note to make a list of the different data types/structures. This appears in the learner view; I'm guessing it...
[This exercise asks the user to create a new script](https://swcarpentry.github.io/r-novice-gapminder/04-data-structures-part1.html#challenge-1). However, there are no instructions on how to create a new script in RStudio in this lesson or how to...
In the section on [checking data for factors](https://swcarpentry.github.io/r-novice-gapminder/04-data-structures-part1.html#check-your-data-for-factors), it says you are ok if you see only “num” and “chr” as data types. However, in my case (and in the...
In the section [on data structures](https://swcarpentry.github.io/r-novice-gapminder/04-data-structures-part1.html) the definition `csv = comma-separated values` is introduced after the term CSV has been used a few times. Consider defining it the first time...
In the instructions on [how to set up a new RStudio project](https://swcarpentry.github.io/r-novice-gapminder/02-project-intro.html#challenge-1-creating-a-self-contained-project), the recommendation is to create a git repo for this project. The instructions don't say anything about what...
In the [Summary and Setup page](https://swcarpentry.github.io/r-novice-gapminder/index.html) the prerequisites for this lesson are: > Understand that computers store data and instructions (programs, scripts etc.) in files. Files are organised in directories...
The exercise on [opening an Rstudio project through the file system](https://swcarpentry.github.io/r-novice-gapminder/02-project-intro.html#challenge-2-opening-an-rstudio-project-through-the-file-system) say to "Navigate to the directory where you created a project in Challenge 1." This could be clarified to...
The lesson gives [instructions to create a self contained project](https://swcarpentry.github.io/r-novice-gapminder/02-project-intro.html#challenge-1-creating-a-self-contained-project). When I go through this, I am also given the option to use renv with this project and whether to...
In lesson 5 ("Exploring dataframes"), learners are taught how to remove rows and columns using "dataframe[- row index, ]" or "dataframe[ ,- column index]". But the concept of indexing is...
