10 months ago @pcofoche Thanks for reporting the two problems. For future reference, it's better to report each problem in separate issues (actually, one of the problems is linked to Rvision and should have been reported on the corresponding repository). This makes tracking progress on separate errors simpler for the developers (in this case, me).
Let's start with the easy one: it is normal that display() does NOT work on Posit Cloud (or on any RStudio Server for that matter). The reason is that display() requires access to the graphical user interface (GUI) of the server which is not possible through Posit Cloud and RStudio Server. These are essentially fancy web servers and they cannot access the GUI of the system they are running on (if any is available – the Posit Cloud server probably has none). You can use the plot() function instead on such servers. However, it is considerably slower than display() when it is available and won't be suitable for applications requiring live display.
Regarding the compilation problem with ROpenCVLite, the error message suggests that there was an earlier error message that was not included in your post. Could you please include the entire output of the compilation process if you can? That would be helpful to find the source of the problem. Thanks.

I have been having an issue with installing ROpenCVLite on my Windows 10 computer for several months. While the installation runs successfully, on Posit Cloud, it gives an error on the local machine and it has prevented me from using the package. Could you please help to look into this?
Many thanks, Paul
Here is my session info:
"R version 4.3.1 (2023-06-16 ucrt)" "ROpenCVLite_4.80.1"
Here is the installation code run: install.packages("ROpenCVLite") ROpenCVLite::installOpenCV()

display() also gives errors when the code is run on Posit Cloud, as shown below:
library(Rvision) balloon <- image(system.file("sample_img/balloon1.png", package = "Rvision")) display(balloon, height = nrow(balloon), width = ncol(balloon))
Could you please help?
Thank you, Paul
