Creating multiple plots within a loop can break the Plot pane

[DavisVaughan]

It seems like only some of the plots will actually render?

From beta user https://github.com/posit-dev/positron-beta/discussions/211

for (i in 1:5) {
  plot(rnorm(10), runif(10))
}

From GH Discussions #4614:

library(ggplot2)
library(purrr)

economics_list <- split(economics_long, economics_long$variable)

# In the RStudio IDE: all images get rendered to the Plots pane, and the user
# can navigate back and forth between the rendered images.
#
# In Positron: only the last image gets rendered, it's impossible to navigate
# to previous ones.
# 
economics_list |> 
  imap(
    \(df, nm) df |> 
      ggplot(aes(date, value)) +
      geom_line() +
      labs(title = nm)
      )

Hello! I'm enjoying Positron and I appreciate the work you are doing.

This particular issue is one I've run into several times in the past month. It's annoying, but fortunately has a simple workaround. I'm looking forward to Positron matching RStudio for multiple plot generation.

fit_lm <- lm(
  mpg ~ cyl + wt,
  data = mtcars
)

# Renders only plot(fit_lm, which = 5)
# Not able to scroll through the which = 1, 2, 3 plots 
# that are automatically called by plot.lm().
plot(fit_lm)

# Workaround
plot(fit_lm, which = 1)
plot(fit_lm, which = 2)
plot(fit_lm, which = 3)
plot(fit_lm, which = 5

This is reported again (I think) in #3363 (comment)
