Charlie Plosser served as a faculty member and Dean of the Business School at the University of Rochester. He served as editor of the Journal of Monetary Economics (with Bob King), and later the President of the Philadelphia Fed. A serious and sensible economist. RIP.

I'm sorry to hear about the passing of Charles Plosser, who led the Philly Fed during the financial crisis. He was definitely old school in his views of central banking's role, and he was generous with his time. When I hear the phrase "systematic monetary policy" I'll always think of him.

Charles I. Plosser passed away on August 14, 2025. Here is an obituary www.hoover.org/profiles/cha...

Among his many influential academic contributions, one might mention "Real Business Cycles" (1983, together with John B. Long).

New on CRAN: ggdiagram (0.1.0). View at https://CRAN.R-project.org/package=ggdiagram
ggdiagram: Object-Oriented Diagram Plots with 'ggplot2'
Creates diagrams with an object-oriented approach. Geometric objects have computed properties with information about themselves (e.g., their area) or about their relationships with other objects (e.g, the distance between their edges). The objects have methods to convert them to geoms that can be plotted in 'ggplot2'.

After I set up a Python environment to run LLMs locally with Docker Model Runner, I wondered if you could use the same workflow with R. The short answer is, "Hell Yeah!"

It took me 5 minutes to run LLMs with R using the ellmer library. Working on a step-by-step tutorial...

I often need to filter data in #rstats based on many variables. The dplyr::if_any() and dplyr::if_all() functions are really handy for this.

More examples here: cghlewis.github.io/data-wrangli...

Missing data is denoted by “MR”. df # A tibble: 6 x 6 id form var1 var2 var3 var4 <dbl> <chr> <chr> <chr> <chr> <chr> 1 10 "a" 3 4 3 3 2 11 "b" 3 MR 2 4 3 12 "b" 1 3 1 MR 4 13 "" MR MR MR MR 5 14 "" MR MR MR MR 6 15 "" 1 2 3 MR # (01) Only keep rows where respondent has missing responses for AT LEAST ONE variable (var1:var4). df %>% filter(if_any(var1:var4, ~ . == "MR")) # A tibble: 5 x 6 id form var1 var2 var3 var4 <dbl> <chr> <chr> <chr> <chr> <chr> 1 11 "b" 3 MR 2 4 2 12 "b" 1 3 1 MR 3 13 "" MR MR MR MR 4 14 "" MR MR MR MR 5 15 "" 1 2 3 MR # (02) Only keep rows where respondent has missing responses for ALL variables (var1:var4). df %>% filter(if_all(var1:var4, ~ . == "MR")) # A tibble: 2 x 6 id form var1 var2 var3 var4 <dbl> <chr> <chr> <chr> <chr> <chr> 1 13 "" MR MR MR MR 2 14 "" MR MR MR MR # (03) Remove rows where respondent has missing responses for ALL variables (var1:var4). df %>% filter(!if_all(var1:var4, ~ . == "MR")) # A tibble: 4 x 6 id form var1 var2 var3 var4 <dbl> <chr> <chr> <chr> <chr> <chr> 1 10 "a" 3 4 3 3 2 11 "b" 3 MR 2 4 3 12 "b" 1 3 1 MR 4 15 "" 1 2 3 MR

Just an honest labor statistician collecting the data, crunching the numbers, and reporting them fairly, and definitely not an extremist ideologue with an axe to grind, unshackled from respect for the law or political norms.

There are some R packages that just feel like magic. I first encountered the datapasta package by Miles McBain when I was working with an EMG system that didn’t export the data in a user-friendly format.

Trump's nominee for BLS commissioner, EJ Antoni, is disastrously terrible. He's a 1200%, 1300% maybe 1400% in-the-tank Trumper, with few credentials beyond a history of misrepresenting or misunderstanding economic statistics. He has shown no commitment to truth
