Errors with Mac OSX Mojave and RStudio

You need to authorize RStudio to use the mic/camera in Mojave. The changes were due to this: https://developer.apple.com/documentation/avfoundation/cameras_and_media_capture/requesting_authorization_for_media_capture_on_macos and fixed here rstudio/rstudio#4579

If you an’t access video/audio from RStudio IDE, then see issue here rstudio/rstudio#4579. If you run into this, make sure you have RStudio version >= 1.3. To access this version download daily build https://dailies.rstudio.com/, authorize (use audio and opencv packages for force auth)

if (!requireNamespace("opencv"))
  install.packages("opencv")

library(opencv)
ocv_video(ocv_edges)

if (!requireNamespace("audio"))
  install.packages("audio")

library(audio)
x <- rep(NA_real_, 50000)
# start recording into x
record(x, 22000, 1)
stopifnot(diff(range(x, na.rm = TRUE)) > 0)

Then download whatever RStudio you want.

• Make sure you go to System Preferences ## Installation

You can install recordscreen from GitHub with:

# install.packages("remotes")
remotes::install_github("muschellij2/recordscreen")
