Thanks for getting back to me, I’m sorry if I was unclear.
What I’m trying to figure out is the equivalent of “find and replace” in Word.
I have a function -
myfun <- function(z){
ggplot(df, aes(x,y)+
geom_point() +
ggtitle (“_______ quick brown fox jumped over the lazy dog”)}
Calling myfun(z) works perfectly. What I’m trying to do is add a string to
myfun so that it would read: function(z, “string”){
Then I could call myfun(z, “string”) to replace the space in ggtitle. Is there
a straightforward way to do that?
