Question

I have a string in R (using RStudio)

legend <- c('Up to 5 minutes', '5-10 minutes', '10–20 minutes', '20–40 minutes', '40–80 minutes', '80-160 minutes', '160-320 minutes', '5.3-10.6 hours', '10.6-21.2 hours', '1-2 days')

which runs fine when I just run the source code by line. But when I source the code it throws an error

Error in source(con, echo = echo, print.eval = print.eval, max.deparse.length = max.deparse.length,  : 
  con:29:52: unexpected INCOMPLETE_STRING

Where could be the problem?

Update from the discussion posted on RStudio:

relevant portion:

I didn’t notice it until now but when starting R I get

WARNING: You're using a non-UTF8 locale, therefore only ASCII characters will work.
Please read R for Mac OS X FAQ (see Help) section 9 and adjust your system preferences accordingly.

Reading the FAQ I did the standard system("defaults write org.R-project.R force.LANG en_US.UTF-8") and now it works fine.
