1/2 R Braintrust, I have a visualization question: I have a raster heat map that represents months on the x axis and hour of day on the y axis and fill is the total of a measurement. Not every hour has value from all days in a moth. How can I cue how complete the data are? #rstats

I heard a really interesting podcast on graph transformers with a key practitioner from Stanford and his company kumo, Jure Leskovec. His work is in Python. Does anyone know if there is any parallel work in R on graph transformers?

In ggplot2, if I’m using scale_y_log10(), is there a way to suppress the axis labels for the minor breaks only if I’m adding minor breaks to the plot? I just want labels on the major breaks.

@spsanderson.com I was reading your post on lookup tables in R. I have found the easiest way to solve the problem is to use main_df <- main_df |> dplyr::left_join(lookup_df). You can deal with the NA’s separately. Is that not a simple and viable solution? And thanks for the tutorials. Very helpful.

I really loved @kjhealy.co’s book Data Visualization (kieranhealy.org/publications...). I know it’s ~5 years old at this point, but it was a great progressive way to work through #gglot as well as the general workflow of #dataviz using the graphics of grammar framework.
