I\'m trying to deal with text with R and here is my question.
From this source text
#Pray4Manchester# I hope that #ArianaGrande# will be better soon.
You could use regex to look for results that match text between two hashes that don't contain a space character.
Something like this: ([#]{1}[^\s]+[#]{1})
We can do
str_extract_all(text, "(?<=#)\\w*(?=#)")[[1]]
#[1] "Pray4Manchester" "ArianaGrande"
text <- "#Pray4Manchester# I hope that #ArianaGrande# will be better soon."
