expanding the idea suggested on mastodon, I analysed the number of questions posted on gis.stackexchange.com over the past decade, focusing on the most popular geospatial libraries in #rstats and #python. The cumsum of daily questions suggests a draw.

Which language serves as the geospatial lingua franca — #pythonor #rstats? A quick look at Google Trends suggests R, but that’s a rather simplistic comparison. Has anyone come across a more in-depth study on the most popular languages for spatial analysis?

I know I'm biased, but maaaan, Formalist and Air work so well together in the latest Positron update.

Dear #rstats, you should give Positron a try.

I was working with big data recently and found that Polars is faster than a DuckDB-based approach. Thanks to {tidypolars} you can use {tidyverse} syntax as well. However, if you are working with a medium-sized CSV like this (only 20K rows), {data.table} may still be faster but it loads csv in memory

Finally got to my laptop and realized I made a mistake. The arrow command is actually open_csv_dataset(). Here is the reprex. Both examples do not load the entire CSV into R, but if your CSV is enormous, it may be beneficial to create an on-disk DuckDB.

There is one more way to tackle this — using `.x` for data masking. I think this is the recommended approach:

my favourite theme in RStudio was {KandleTheme} (github.com/TheMrKingent...) with {darkstudio} enabled (github.com/rileytwo/dar...). They are perfectly work together. Just look at this beauty

Consider this: to slow down #AI development, the community could deliberately mislabel correct answers as incorrect. By doing so, the false positive rate would rise, confusing the #LLM and disrupting its learning process. 🤖🤔

A couple of years ago, I saw this life hack on Twitter and cannot commend the unknown author enough. This is the best use of pop sockets! Very handy for reading kindle on the go

🎉 New in Formalist for Positron IDE: Fix lints in #rstats code on demand!

Select your code, hit a button, and let {flint} by @etiennebacher.bsky.social handle the rest.

🚀 Works on selected text only
🔧 Customizable with flint::setup_flint()

Works ONLY in Positron starting from v2025.01.0, as it depends on the latest features @juliasilge.com and the team added to the IDE's API (thank you guys 🙏).

Users can now run #rstats code in the background with positron.RuntimeCodeExecutionMode.Silent

Day 2 of porting my favorite RStudio addons to Positron. Introducing Formalist, an extension that allows you to make R function calls explicit, i.e., from select(mtcars, cyl) → dplyr::select(mtcars, cyl). It uses {pedant} #rstats 📦 by @wurli in the background!

What a trailer and review by David Ehrlich ♥️ #Parthenope

Parthenope’ is just a long movie made by a middle-aged man who almost drives himself insane trying to imagine what life would be like as an unbelievably hot woman.

You should try to run Positron on WSL as well. Setting "window.titleBarStyle" to "custom" helped a lot with full integration into the Windows system. There will be no ugly frames around the window.

Looks like Rewrap does what you need. See example below. I have just set "rewrap.autoWrap.enabled": true and "rewrap.wrappingColumn": 80 in the extension settings

Hey, #rstats has anyone used cursor.ai for development? I'm curious, are you using `.cursor_rules`? I recently tried creating one and TBH, it works mediocre; it seems like most of my rules were ignored. Please share yours if you have any!
You are an expert in geospatial data analysis and visualization in R, with a focus on libraries including `sf`, `geos`, `wk`, `terra` and `duckdb`. ### Key Principles: - Write concise, accurate R code examples, focusing on geospatial workflows. - Prioritize readability and reproducibility in all code. - Use the `|>` pipe operator for a clear, readable pipeline structure. - Favor functional programming and modular code; avoid unnecessary global variables. - Use descriptive variable names reflecting geospatial data attributes and structures. - Follow Tidyverse and R style guidelines (avoid redundant comments; use consistent indentation and naming). ### Geospatial Data Manipulation: - Prefer `geos` and `wk` over `sf` and `terra` workflows where possible. ### Data Integration and Conversion: - Convert between formats using the fastest approaches (usually `wk`). - Use `st_as_sf()` and related functions to ensure interoperability between `sf` and `terra` objects when mixing vector and raster data. - Handle large datasets efficiently by writing some data at disk using `duckdb` or by storing geometries as `wkt`. ### Best Practices for Package Development: - Structure code into modular functions, avoiding redundant operations. - Include descriptive error messages using `rlang::abort()` for custom error handling. - Document each function with clear input-output descriptions, focusing on expected spatial data types. ### Error Handling and Data Validation: - Perform data quality checks on input geospatial data (e.g., using `st_is_valid()` to check geometry validity). - Validate coordinate reference systems (CRS) to ensure compatible projections between layers. - Handle missing data with appropriate methods (e.g., imputation, exclusion) to avoid display or processing errors in visualizations.

Huge update to the {pastum} VS Code extension — you can now control the decimal separator (point or comma). Paste as default dataframe is now sensitive to the editor language, so you can easily paste in your favorite format with just one click. See some showcases below.

Great intro! I have been using it for months and there are almost no issues. If there are any, the @posit.co is very responsive on GitHub! BTW Positron does not support automatic updates yet, but windows-folks can do it semi-manually via scoop.sh and the r-bucket maintained by @cderv.bsky.social
# Add bucket ❯ scoop bucket add r-bucket https://github.com/cderv/r-bucket.git # Install Positron ❯ scoop install positron # Update when necessary ❯ scoop update positron # positron: 2024.11.0-116 (latest version) # Latest versions for all apps are installed! For more information try 'scoop status'
