I have the following problem when starting RStudio and when I try to compile a PDF from a .rnw format:
Error: '\U' used without hex digits in character string starting ""C:\U"
When starting RStudio or just R this is what is inside my console:
R version 3.4.0 (2017-04-21) -- "You Stupid Darkness"

Global .Rprofile loaded!
Error: '\U' used without hex digits in character string starting ""C:\U"
And this happens when I try to compile a PDF:
Global .Rprofile loaded!
Error: '\U' used without hex digits in character string starting ""C:\U"
Execution halted
This kind of appeared from one day to another and I am not sure what has changed. I tried updating RStudio and my R-version, but it did not help. I am running R on Windows.
Can anybody help me with that issue?
I was able to solve this after all:
I had a section inside my .Rprofile file (in Documents) with "\" instead of "/". So I now changed
# Set mainfolder for PACKAGE package
options(PACKAGE_MAINFOLDER="C:\Users\...")
to
# Set mainfolder for PACKAGE package
options(PACKAGE_MAINFOLDER="C:/Users/...")
and that did the trick.
