How to strsplit using '|' character, it behaves unexpectedly?

Question

I would like to split a string of character at pattern \"|\"

but

unlist(strsplit(\"I am | very smart\", \" | \"))

[1] \"I\"     \"am\"    \"|\"              


        

Answer 1

Pipe '|' is a metacharacter, used as an 'OR' operator in regular expression.

try unlist(strsplit("I am | very smart", "\s+\|\s+"))
