#function to substitute vowels with Maori macrons into text strings in R
#there's probably a fancier way to do this, but it works OK.
#just precede vowels requiring a macron with '@' and the function will substitute the appropriate vowel with macron.
#Handy for graph labelling etc.
x<-gsub("@a","\u0101", x) #macron a
x<-gsub("@e","\u0113", x) #macron e
x<-gsub("@i","\u012B", x) #macron i
x<-gsub("@o","\u014D", x) #macron o
