This is basically a shameless spin off of https://stackoverflow.com/questions/57330300/how-to-reproduce-hypertools-clusters-identified-from-hypertools-plot

I am trying to take the results of using hypertools.plot(...), but my attempts to replicate them by using other parts of hypertools are yielding surprisingly different results.

I would like some guidance on this, but I also feel like ha

Because some user has had problems configuring these services could be helpful to make some examples or videos about how to properly setup Optimus in this services.

Add how-to documentation for inequalities.

Should demonstrate:

• using validate.interval() to create left- and right-bounded intervals (for greater-than-or-equal-to and less-than-or-equal-to)
• using functions for implementing greater-than or less than (but not equal-to)
• and maybe interval disjunction (e.g. a combined x < min or max < x)

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

The text uses two different articles when referring to files with the .R extension (i.e. "an .R file" and "a .R file"). This should be standardized. When referring to the file extension in speech, the ".R" is generally spoken as "dot are", so using the article "a" seems most appropriate.

The help pane could use additional calling out; the section describing mathematical functions (sin/cos/t

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 the Making Plots With plotnine lesson, there is a disclaimer that shows how to load plotnine.

I would recommend also mentioning here a reminder that plotnine is not in the standard Anaconda package and needs to be installed separately.

In this lesson, we learn that you can use a slice to get a substring and that "Numbers are not stored in the written representation, so they can’t be treated like strings." However, what about adding a short follow up to this part of the assignment to teach the students how to convert an integer to a string? For example, if you type in the code:

a = str(123)
print(a[1])

instead of the code

In episode _episodes_rmd/12-time-series-raster.Rmd

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

These are the planned activity for 0.3.0
These are in progress in nightly
Few of these may be dropped (as all of these are experimental)

• Complete Heuristic maturation phase 1 : complete r-rudra/tidycells#5
• Introduce grammar
• %<^% kind of symbols for NNE etc.
• Add shinytest prototype as de

Currently, these words 404 as they are pointing at https://swcarpentry.github.io/reference.html#relational-database. They should be pointing at https://swcarpentry.github.io/**sql-novice-survey**/reference.html#relational-database. Looking at the code, this is rendered

The current version of DB SQLite doesn't have the tabs or organization described in the module. As a novice, without being able to actually follow the instructions, it's unclear what the purpose of the instructions are.
