R warnings on Mac

Dear friends,

This was my oldest warnings that I haven't blogged.

It was when I run R on my Mac for the first time, few years a go. 

The following warnings popped out when R was starting:

1: Setting LC_CTYPE failed, using "C"

2: Setting LC_COLLATE failed, using "C" 

3: Setting LC_TIME failed, using "C" 

4: Setting LC_MESSAGES failed, using "C" 

5: Setting LC_PAPER failed, using "C"

The problem was something about the default encoding and language between your Mac and R that were not matched.

I found solution on stackoverflow by typing (or copy pasting) the following script:

defaults write org.R-project.R force.LANG en_US.UTF-8

in your Mac terminal.

Then the warnings disappeared when you start R.
