hello,
i wonder how is string represent in R. if i have a string s= "hello", how can i
refer to first character in the string s?
also if i have s1 = "hello.1", s2 = "ok.1", how can i separate the s1 into
"hello" "1" and s2 into "ok" and "1"? I have tried to use the substring
function, but i don't where i can get the index for "." in the string?
Thank you so much
