The Unix Shell: Lesson 4. Pipes and Filters
Word count without flags is used to initially introduce the command and outputs three points of data - character, word, and line count. Then -l is added to show how line count is attained. It would be helpful to also include wc -cwl to show that the output is the same as default without flags. This would help by teaching about default flags and also inc

The first episode is more a description of "a" version control system, rather than of Git. I think that's useful as this is the first exposure of many learners to the concept. Also, the model based on diffs in not completely accurate for Git. A compromise to be both accurate and keep it simple could be to change the second objective to reflect this. So, what about?

Understand the basics

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

(This issue is specifically created as my contribution for the instructor training checkout process.)
Can we have a section in this lesson which will explain the ways in which one can change the names of the columns of a data frame in R?

Admittedly, I'm not a pythonista, but I wonder whether there would be value in using bash versions of the three python scripts. For whatever reason, I'm running into problems with getting python installed correctly on my Mac. Once I got it pointed in the right direct, I ran into problems with installing numpy. It's quickly becoming a tutorial on installing python rather than make :)

I suspect the

Dear Community,

There is a typo in the section titled "The StringsAsFactors argument" after the second block of code that demonstrates the use of the str() function. Right after the code boxes is written "We can see that the $Color and $State columns are factors and $Speed is a numeric column", but the box shows that the $Color column is a vector of strings.

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

Hi,

As part of the checkout process for carpentries, it is encouraged that we provide feedback to one of the modules. Going through the Python Novice Mindgap section on li

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....

Per #260, using tibble::glimpse to peek at parsed json tibble. It would be nice to introduce glimpse in Starting with Data episode.

The Survey table has a field called quant that holds what type of reading was taken. The values in this column are rad, sal, and temp. There is no legend that explains what these mean on the page where the data is introduced (the selecting data chapter). Much later in the course it's mentioned that these mean 'radiation', 'salinity' and 'temperature', but I think it would also be helpful
