I built my package successfully and then I made an update to the "Description" and "Namespace" files and may have made some project configuration setting changes.
Now, when I try to build, "Build Source" works but "Build Binary" fails. I have no idea how to troubleshoot this error (I am a newb to R and RStudio) but I get the following error. Note, my old package works the way I want it to; I was mainly trying to update the "Description" so I can distribute the files nicely to a colleague. However, the package fails even if I copy the original "Description" and "Namespace" files back into the work folder. The following is the output message (I have no idea what to do with the "Try '/Rtools/bin/cp --help' for more information." message).
