bivariate spatial correlation in R
Rafael Pereira · Aug 6, 2017 · r-sig-geo

Hi Roger, you're correct in pointing out that the code would much more work to be incorporated in the spdep library. This is something that Rogerio and I are considering to do in the next few months as both...

bivariate spatial correlation in R
Rafael Pereira · Aug 2, 2017 · r-sig-geo

Roger, Thank you for your response. I recognize the data is not ideal and the analysis has limitations because of the lack of information on population displacements that might have occurred over the years. Nonetheless, there are plenty of data...

[R-pkg-devel] Falling gracefully in subsequent code
Rafael Pereira · Jan 1, 2026 · r-package-devel

Thank you all for the kind suggestions! Dirk's advice (in the same spirit of Hadely's suggestion) should work like a glove ! For the record, I really appreciate how supportive the R community (and this group in particular) is...

bivariate spatial correlation in R
Rafael Pereira · Jul 30, 2017 · r-sig-geo

Roger, Population and income data are single point in time and come from the 2010 Census. Accessibility variables in 2014 and 2017 show the proportion of jobs accessible by public transport under 60 minutes. The variable diffaccess shows the difference...

bivariate spatial correlation in R
Rafael Pereira · Jul 29, 2017 · r-sig-geo

Hi all, here is a reproducible example to calculate in R bivariate Moran's I and LISA clusters. This example is based on a this answer provided in SO* and it uses a toy model of my data. The R...

[R-pkg-devel] CRAN pending status , left up in the air
Rafael Pereira · Oct 19, 2020 · r-package-devel

Thank you Dirk and Hugo for your responses. I guess I'll just have to be patient and wait. I can only imagine how the CRAN team is overwhelmed by the exponential growth of package submissions. I wonder, though, whether...

[R-pkg-devel] Falling gracefully in subsequent code
Rafael Pereira · Dec 29, 2025 · r-package-devel

Hi all, I would very much appreciate your thoughts on this situation. # context I received an email from Prof Ripley saying that my package is not "falling gracefully". Error report here https://www.stats.ox.ac.uk/pub/bdr/Rblas...

bivariate spatial correlation in R
Rafael Pereira · Jul 26, 2017 · r-sig-geo

Roger, This example was provided only for the sake or making the code easily reproducible for others and I'm more interested in how the bi-variate Moran could be implemented in R, but your comments are very much welcomed...

[R-pkg-devel] Retrieving versioned csv datasets for use in an R package
Rafael Pereira · Feb 14, 2025 · r-package-devel

Hi John, There are different alternatives on where to host the data (e.g. OSF, a proprietary server, Github etc). The solution I've been adopting in most of my packages is to use a combination of a proprietary server...
