R中带连字符的字符串

Question

我在R中有一个字符串(使用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')

当我只是逐行运行源代码时运行正常.但是当我获取代码时,它会抛出一个错误

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

哪里可能是问题？

从RStudio发布的讨论更新:

直到现在我才注意到它,但是当我开始RI时

阅读常见问题我做了标准system("defaults write org.R-project.R force.LANG en_US.UTF-8"),现在工作正常.
