geocompx / geocompkg

A metapackage containing vignettes used in the book Geocomputation with R

geocompkg

This is a ‘metapackage’ support the book Gecomputation with R. Installing installing it will give you the dependencies needed to run the code in the book. The repository also contains additional materials to supplement the book. See the vignettes folder for the source code.

Installation

You can install the packages needed to reproduce the code in Geocompuation with R by installing the geocompkg package as follows:

devtools::install_github("geocompx/geocompkg")

Alternatively, you may install this package using the R-universe repository:

options(repos = c(
  geocompx = 'https://geocompx.r-universe.dev',
  cran = 'https://cloud.r-project.org'
))
install.packages("geocompkg")

If you have any issues, check-out Chapter 2 of the book.

Use of the tidyverse package in the DESCRIPTION

@Robinlovelace @jannes-m would it be possible to replace the tidyverse package in the DESCRIPTION (https://github.com/geocompr/geocompkg/blob/d4af9b8c3dca6bf4f9e28083f1d71646f0cf9d9c/DESCRIPTION#L54) with a set of packages that we actually use? What do you thing?

Build failing

Heads-up @Nowosad, just noticed this is failing on the universe builds: https://github.com/r-universe/geocompr/runs/3383708750?check_suite_focus=true and maybe on actions too...

Build failing due to solutions vignette

From @Nowosad: https://github.com/geocompr/geocompkg/runs/881351939?check_suite_focus=true - we need to update the solutions vignettes

Any ideas @Nowosad ?

Not sure where to edit - error Chap 4 solution

Hi! Not sure where to put the pull request for the solutions.html

Code as in solutions:

canterbury = nz %>% filter(Name == "Canterbury Region")
canterbury_height = nz_height[canterbury, ]
nrow(canterbury_height) # answer: 61

Problem:

 Canterbury Region" %in% nz$Name
 [1] FALSE
 "Canterbury" %in% nz$Name
 [1] TRUE

Suggested solution:

canterbury = nz %>% filter(Name == "Canterbury")
canterbury_height = nz_height[canterbury, ]
nrow(canterbury_height) # answer: 70

Reduce reliance on dev versions of packages

We still rely on 4 packages not on CRAN:

    mlr-org/mlr3extralearners,
    mlr-org/mlr3spatiotempcv,
    mlr-org/mlr3proba,
    paleolimbot/qgisprocess,
    nowosad/spDataLarge,

An issue associated with this is that if you run

remotes::install_github("geocompr/geocompkg", dependencies = TRUE)

On the majority of computers that have not been authenticated with GitHub, you may get an error message along the lines of the following, if other packages have been installed from GitHub:

Downloading GitHub repo mlr-org/mlr3proba@HEAD
Downloading GitHub repo alan-turing-institute/distr6@HEAD
Error: Failed to install 'unknown package' from GitHub:
  Failed to install 'unknown package' from GitHub:
  Failed to install 'unknown package' from GitHub:
  Failed to install 'unknown package' from GitHub:
  HTTP error 403.
  API rate limit exceeded for 51.154.68.67. (But here's the good news: Authenticated requests get a higher rate limit. Check out the documentation for more details.)

  Rate limit remaining: 0/60
  Rate limit reset at: 2023-05-21 12:08:42 UTC

  To increase your GitHub API rate limit
  - Use `usethis::create_github_token()` to create a Personal Access Token.
  - Use `usethis::edit_r_environ()` and add the token as `GITHUB_PAT`.

This is not good for reproducibility, especially for beginners. Is there any way we can move away from dependency on any of these GitHub packages or can we help their maintainers submit to CRAN?

Thoughts v. welcome @jannes-m and @Nowosad or anyone.

Update tidyverse pitfalls vignette

Blog post on animating trajectories

I've been experimenting with this and have some examples:

and

Unfortunately there seem to be severe limitations on what is currently possible in this space: no easy way to add a time slider as far as I can tell. Heads-up @tim-salabim just in case but I plan to write a post showing how to get the basics going and doing a bit of a 'call for developer' time to solve what should be a fairly straightforward problem. On a related note, it's pretty amazing to see what is possible in animated web mapping these days:

Not able to reproduce the figure 2.5 (page 27)
