On http://rspatial.org/analysis/rst/6-local_regression.html

library( spgwr )
## Error in library(spgwr): there is no package called 'spgwr'
bw <- gwr.sel(pan ~ ALT, data=spt)

How to get the air quality dataset in Chapter 16 Interpolation and Geostatistics

Hello. I'm reading the book Spatial Data Science. It's awesome! I like doing spatial staff in the sf way~

In chapter 16, although the URL of air quality data is provided, and it is said:

It returns a text file with a set of URLs to CSV files, each containing the hourly values for the whole period for a single measurement station. These files were downloaded and converted to the right encoding using the dos2unix command line utility.

I'm still confused about how to get the data in the right place so that I can follow the chapter. Could you please provide more details?

Many thanks for your help!

MazamaSpatialUtils package

Another package for potential inclusion in the list:

https://CRAN.R-project.org/package=MazamaSpatialUtils

A suite of conversion scripts to create internally standardized spatial polygons data frames. Utility scripts use these data sets to return values such as country, state, timezone, watershed, etc. associated with a set of longitude/latitude pairs. (They also make cool maps.)

Add blog post on spatial networks with sf

Heads-up @edzer, anything else we need to do to get this hackathon up there? https://github.com/spnethack/spnethack/blob/master/blogpost.md

Cc @luukvdmeer and @loreabad6 - finally we can get this out there!

view raw Rmd seems to be a broken link

When I click on View raw Rmd it takes me here that gives me a 404 error

https://raw.githubusercontent.com//r-spatial/r-spatial.org/gh-pages/_rmd/2018-10-02-ggplot2-sf.Rmd

Removing the extra / seems to fix it.

Re: latest sf/ggplotblog posts, facetting, rnaturalearth

These are 2 suggestions for improving the three (really good) blog posts recently published regarding plotting spatial data with ggplot2 and sf.

I wasn't sure where to leave these, as I do not know how to reach the authors.

1. I personally use facetting in ggplot quite often, way more often than I use cowplot or patchwork to arrange plots manually. Of course facets work well with sf data, they look clean and you do not have to bang your head around to find the proper size ratios. The downside is that they are, of course, much less flexible. E.g. you cannot plot two different physical dimensions next to one another, but you can plot the same thing from different datasets.
2. I find grabbing spatial data from rnaturalearth, rnaturalearthhires and rnaturalearthdata is much more convenient than using maps or rworldmap. These packages interface to http://www.naturalearthdata.com/, optionally providing sf objects as output. One neat and useful thing is that if you grab, for example, both country boundaries and municipalities, they match exactly, avoiding small and ugly differences which come from using datasets from different sources.

How to I correct a type on http://rspatial.org/spatial?

Usually there's a link to the github source, and I can submit a pull request.

Retirement of maptools

Hello,

I am assisting in developing a package that depends on maptools (specifically the sunriset method). Loading the package displayed a warning about impending deprecation of the package, and pointed to this blog: https://r-spatial.org/r/2023/05/15/evolution4.html
However it's not clear where (if anywhere) those functions have been rehomed. Is someone able to provide some guidance? I'm happy to contribute with pull requests if that's helpful.

Apologies if this is not the correct place for this question, but hopefully someone can help.

Thank you!

Add r-spatial.org to R-bloggers

I noticed r-spatial.org is not on the list of R-bloggers blogs: https://www.r-bloggers.com/blogs-list/

The onboarding is quite simple. I'd say we can just use the regular RSS feed because all posts are related to R. I would be happy to do this if welcome., i.e. if the contributors are happy to have the content appear on the R-bloggers site.

• submit at https://www.r-bloggers.com/add-your-blog/
• add R-bloggers to blogroll (already the case)

Add blog post about useR! 2020 Geospatial Dev Day

Is this something that would make sense on this blog @edzer? Or is this better suited for a different venue?

If so, I'll go ahead and write something up to share.

Homepage set to wrong URL ?

The homepage of the r-spatial github organization is set to another organization, https://github.com/rspatial. I am not sure if this is intended, but this property is also used to get the official homepage of the "r-spatial" organization by other front-ends, for example https://r-spatial.r-universe.dev/ which is pretty confusing.

Update stars blog post

The example from the stars post which is referenced in the readme no longer works :( Has st_stars been renamed to read_stars?

Date of RSAGA blog post got updated accidentally

From March to October: https://www.r-spatial.org/r/2018/10/20/rsaga-1.0.0

However, I do not see any change in the corresponding files or the commit history.

Probably happened when the "Drawing beautiful maps programmatically with R, sf and ggplot2" posts were added.

Nothing problematic and it probably takes too much time to debug this for now.
Just wanted to let you know. Feel free to close the issue after reading.

Fix URL to SDSL page

On the https://r-spatial.org/ website, the Spatial Data Science across Languages (SDSL) link directs to https://r-spatial.org/sdsl/index.qmd, rather it should to https://r-spatial.org/sdsl/.
