Hello,
In "Working with Files and Directories" under "Good names for files and directories" I think it would be good advice to suggest that file names contain only lower case letters. If nothing else, it would be worthwhile to emphasize the importance of being consistent with letter case when choosing file names.
My understanding is that Unix is always case sensitive, while Windows is not, an

In Episode 8: Collaborating, there are many gendered pronouns that should be changed to better fit with the model of inclusivity that the Carpentries has built.

To accept access to the Owner’s repo, the Collaborator needs to go to https://github.com/notifications. Once there she can accept access to the Owner’s repo.

In the Manipulating data episode it says

You may also have noticed that the output from these calls doesn’t run off the screen anymore. It’s one of the advantages of tbl_df over data frame.

This is the first place the term tbl_df is used in this lesson, and it is not clear that this means tibble.

For context, see swcarpentry/python-novice-inflammation#887

Maintainers would like to solicit contributions to update episode 1 with examples more relevant to the inflammation story.

1. As a Matrix user, write a message in a bridged room.
2. Edit the message, so it's longer than Slack's maximum for messages.

The space between Work and flow in the title of the Work flow within RStudio chunk should be removed as workflow is a single word.

Also, in this same section, reference to a .R file occurs without explanation that this is reflective of the R scripts described above. This could potentially b

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

• I felt like nunique was arbitrarily (re)introduced when it was necessary. It wouldn't be top-of-mind for students solving problems.
• The lesson answers need to be adjacent to the exercises.
• I like the pre-introduction of masks and then circling back around to explain them.
• I feel like Part 4 needs to be broken up and integrated across other lessons: it felt thin on its own.

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.

Regards,

The solution to the "Cumulative Sum" challenge in Episode 12 uses the augmented assignment operator += without comment or explanation. In the rest of the episode, the more verbose total = total + whatever syntax is used. The only other occurrence of += is in Episode 18.

My feeling is that += i

There is a big chunk of code that can probably be made to look nicer via dplyr:

# Plot RGB data for Julian day 133
 RGB_133 <- stack("data/NEON-DS-Landsat-NDVI/HARV/2011/RGB/133_HARV_landRGB.tif")
 RGB_133_df <- raster::as.data.frame(RGB_133, xy = TRUE)
 quantiles = c(0.02, 0.98)
 r <- quantile(RGB_133_df$X133_HARV_landRGB.1, q
