When I turn on my R project, this strange error occurred.
Error: 1:41: unexpected string constant

I reinstalled it twice, but the same problem happened. The same problem occurred when installing the lower-version(3.3.1).
Due to this error, I can not make any R markdown document.

I'm really want to know how to deal with this strange error. Thank you!

I'm running some very simple code:
library(opencv)
ocv_video(ocv_face)
And the session immediately aborts.
Any ideas? (note: running R 4.0.2)

Solution
For anyone else who arrives here, the solution is to run the same code from terminal. That is press cmd + space to bring up spotlight search, type terminal to open terminal. Type R to open the R interpreter, and use that instead of RStudio.
Cause of the crash
The reason it works from terminal but no RStudio is because from terminal, a prompt will appear asking you to give opencv permission to use your webcam, but this prompt will not appear in RStudio (it causes the crash).
In some ways this is a continuation of this older post, R packages with Rcpp and nloptr.
Mostly, this solution proved temporary, for several reasons, some minor, but mostly I am working to prefect this project for a cran submission and this remains the last hurdle.
That said, I attempted and failed to get this example running https://github.com/jyypma/nloptr/issues/39.
The error here is "..../sourceCpp_2.so Reason: image not found"
After, this I made a test package with nlopt installed into the 'inst' folder and 'makevars' and 'makevars.win' in the 'src' along with the test example from above.
This package is now on GitHub: https://github.com/shortyatz/Nlopt-and-Rcpp.
And gives me a similar error message to the one above.

My problem on my MacOS is that I can use R from GUI (aka console, downloaded from CRAN), Terminal or from RStudio but I cannot have them function in the same way.
Specific example is I can use rJava on Terminal and RStudio but not on GUI. Similar stuff happens for Rmarkdown pdf outputs. I usually get errors from GUI but everything is fine on Terminal or RStudio. How do I update R GUI settings to the same as Terminal's?
ps. For instance R CMD javareconf command handled the Terminal R but not R GUI.
edit: It is not actually something that requires a minimal working example but let's try library(rJava) after installing it.
R Called from Terminal (same with RStudio)
No problems.

Some differences between Sys.getenv() are GUI has the following extra
LD_LIBRARY_PATH :#JAVA_LD#
DYLD_LIBRARY_PATH /Library/Java/JavaVirtualMachines/jdk-10.0.1.jdk/Contents/Home/lib/server
Brief update: I was able to correct Rmarkdown situation by using this link and reading help by writing ?Startup on R console. Changed the Renviron file on my R.home()/etc/. But still no rJava.
For R Markdown problem, I managed to handle it by adding a ~/.Renviron file and defining PATH parameter with the value I got from Terminal's Sys.getenv() parameters.
The only thing that worked for rJava for High Sierra is the following answer (changed the version to 3.5 though)

I am using R 3.2.2 and RStudio 0.99.486 (latest version) under Windows 7 SP1 64 bit. I always get an error when I start RStudio:
the procedure entry point vsnprintf could not be
located in the dynamic link library R.dll
But I don't get any errors when I directly start R 3.2.2.
The R installed into C:/ProgramFiles/R/R-3.2.2/ (not the default path) and don't have other versions of R. RStudio is setup to use the installed R.
Except I get an error in RStudio, all my R codes can run in RGUI and RStudio.
Thanks for any suggestions to solve this annoying problem.
