reprex with a plot fails (because imgur upload fails due to the API key quota being exhausted)

[DavoOZ]

The following code, when selected in RStudio and submitted to {reprex} via the Addins menu ("Reprex selection"), causes the R session to crash. Not sure why. Code runs fine from the Source pane.

suppressPackageStartupMessages(library(tidyverse))
library(relaimpo)

# Regresses first column (mpg) against the other 10 variables
model <- calc.relimp(mtcars,
                     type = c("lmg","last","first","pratt"),
                     rela = TRUE)
plot(model)
str(model)
summary(model)

mod.df <- data.frame(lmg = model$lmg * 100,
                     first = model$first * 100,
                     last = model$last * 100,
                     pratt = model$pratt * 100)
mod.df

mod.df %>%
  rownames_to_column(var = "Variable") %>%
  pivot_longer(cols=2:5,
               names_to = "Method",
               values_to = "% of R2") %>%
  arrange(Method, Variable) -> long.df

head(long.df)

ggplot(data=long.df) +
  aes(x=Variable, y=`% of R2`) +
  geom_col() +
  facet_wrap(~ Method, nrow=2, ncol=2) +
  labs(title=(paste("Relative importances for", names(mtcars)[1])))

^{Created on 2025-01-13 with reprex v2.1.1}

[juliasilge]

Here is a simpler reprex, as found in posit-dev/positron#5969:

reprex::reprex({
	x <- rnorm(100)
	plot(x, sin(x))
	})

If you look at std_out, it's failing to upload the image to imgur:

Standard output and error

Quitting from lines 20-22 [unnamed-chunk-2] (steep-carp_reprex.spin.Rmd)
Error in xfun::upload_imgur(file, key, ..., include_xml = TRUE) : 
  Failed to upload steep-carp_reprex_files/figure-gfm/unnamed-chunk-2-1.png (reason: 1025)

I will highlight that there was a brand new release of xfun a few days ago.

The full story is at yihui/xfun#97. The key used for imgur uploads, which any reprex with a plot will tickle, by default, is out of service, with "too many requests". It's unclear why or if the situation is permanent.

So I'll keep an eye on this for a bit. If fortune smiles, the key will start working again, maybe after some suitable period of time has passed. Otherwise, we'll have to take some more measures to use a different key or make it more obvious to reprex users how to provide their own key.
