Strange graphical output for simple epicurve

[gfspiteri]

I have been producing simple epicurves for the outbreak of COVID-19. Last Friday my outputs started acting weirdly with data not being plotted and the x-axis disappearing (I don't know that I changed anything/installed any new packages/upgraded anything etc). I tried using simple examples from the incidence package help file and again got very strange outputs. For example:

library(outbreaks)
library(ggplot2)
library(incidence)
dat <- ebola_sim$linelist$date_of_onset
i <- incidence(dat)
plot(i)

leads to

This is my sessionInfo() output:

Thanks for the report. It is very weird. I'll try and see if I can reproduce it with the latest version of R.

Will address today.

This looks like some buggish behaviour of ggplot2::aes_string. Working on a workaround

[thibautjombart]

Now reported the bug to the Rstudio crew: tidyverse/ggplot2#3873

@gfspiteri can you try installing this patch:

remotes::install_github("reconhub/incidence@issue_119")

And let me know if it fixes your issue?

[gfspiteri]

Thanks yes works well both for the ebola data and my script.

[thibautjombart]

Great, thanks. I have submitted a PR. This will be in the next release on CRAN, hopefully soon as this is a major bug. Thanks for reporting it!

[gfspiteri]

Thanks for responding so quickly!

[thibautjombart]

Reopening because the problem still exist on master, until the PR goes through
