When creating a Shiny app, stop and think: What is Shiny-specific (like inputting data) and what is not Shiny-specific (like generating a dataviz based on specific inputs). If it's not Shiny-specific, put it in a function @tanho tells #ShinyConf2023

GREAT talk by @tanho on debugging Shiny apps at #ShinyConf2023. Slides are here

But it would definitely be worth watching the talk video when it's available if you missed it

Excited today that my InfoWorld "Do More With R" series was named a Jesse H. Neal Award finalist for Best Instructional Content!

I'll be competing with colleagues at Computerworld as well as 2 others for this 😀

My RStudio code snippets to get an object from a character string and get the object name as a strong from the object:

snippet string2obj
eval(parse(text = "${1:obj_name}"))

snippet obj2string
deparse(substitute(${1:obj_name}))

You can use Google Sheets to automatically fetch and save data on a schedule - even without an external programming language like Python or R. Here's my step-by-step tutorial:

I *really* want to try out the {bslib} #rstats 📦's new cards feature -- especially in a Quarto doc (without needing a Shiny server). On the to-do list!

@appsilon 's sample code to create a 2-level drilldown bar graph in an R Shiny app is very easy to use!
Data structure is super simple: 4 columns, 1 for each level and a 4th for the value. Then create a #DataViz with the {echarts4r} #rstats 📦 using their example.

Code with basic #RShiny app: https://raw.githubusercontent.com/Appsilon/community-gists/main/echarts4r/drill_down_example.R

@camartinezbu @MikeMahoney218 I've used R a lot more than QGIS, but I find the {mapview} #rstats 📦 easier for quick prototyping.You can't get much simpler than

mapview(mydata, zcol = "mycolumn")

For a choropleth map!

The {stringr} #rstats 📦 gets a function to convert a character vector into a single, comma-separated string *with custom wording before the last item.* (I've been using knits::combine_words() for that.)

Example from the tidyverse blog post about stringr 1.5.0:

str_flatten_comma(c("cats", "dogs", "mice"), last = ", and ")

#> [1] "cats, dogs, and mice"
