I am writing a Shiny app and have packaged the entire app into a package. Let's call this app/package fruit
Every time I made changes to the app, I would do the following:
library(devtools)
install()
library(fruit)
run_fruit_app()
I suspect that I messed up something while editing, now after I run install(),
the following error messages pops up:
Running /Library/Frameworks/R.framework/Resources/bin/R CMD INSTALL \

What could be potential source of errors? I did make sure that I did not forget to close a bracket, used a wrong bracket, or set things in the wrong working directory.
Any insights are much appreciated!
As mentioned in the comments, I recommend you do :
library(devtools)
check()
load_all()
run_fruit_app()
instead of installing the package every time you need to check something.
Also, check() will tell you if there are problems with your code. I guess you have a call to library() somewhere in your code.
Finally, I also have a shiny app that is packaged. Just in case you need to check something, this is the link to the repo https://github.com/tomicapretto/sdeshiny
Good luck!
