Thank you for your input, andresrcs!
I am not quite following here. I tried setting the code in my console as you suggested. options(encoding = "UTF-8").
Then I attempted to run the App on my local server. It gave me an error as this:
Warning in readLines(file, warn = FALSE) :
invalid input found on input connection 'www/SymptomData.R'
Error in source("www/SymptomData.R", local = T) :
www/SymptomData.R:28:32: unexpected INCOMPLETE_STRING
27: PWHO<-PWHO[,-c(3:5,7:13)]
28: rownames(PWHO)[rownames(PWHO)=='Côte d
^
After I deleted certain lines of code, it gave me another error as:
Warning in readLines(file, warn = FALSE) :
invalid input found on input connection 'www/SymptomData.R'
Warning in file(file, "rt") :
InternetOpenUrl failed: 'The operation timed out'
Error in file(file, "rt") : cannot open the connection
Was I doing your way correctly?
Many thanks and stay healthy!
