Incompatible class ordering with `tidyverse`

[FinYang]

Is the package still maintained?

fbi/R/fredmd.R

Line 159 in 9de0e15

class(outdata) <- c("data.frame", "fredmd")

It's better to have

class(outdata) <- c("fredmd", "data.frame")

library(fbi)
library(tidyverse)

dat <- fredmd("https://www.stlouisfed.org/-/media/project/frbstl/stlouisfed/research/fred-md/monthly/2026-04-md.csv") 
dat |> 
  filter(date < as.Date("2026-04-01"))
