Czech encoding in R

Question

I have installed RStudio on a new computer, and has developed encoding issues. When I type accented text in console (no file writing or reading involved, just plain console)

Answer 1

Perhaps:

new.locale <- ifelse(.Platform$OS.type=="windows", "Czech_Czech Republic.1250", "en_US.UTF-8")
Sys.setlocale("LC_CTYPE", new.locale) 

Also learn to specify your OS.
