How to repeat a String N times in R?

Question

In Ruby I could repeat a String n times with the following:

E.G. "my_string" * 2 -> "my_stringmy_string"

Is there an equally simple way for doing this in R?

Answer 1

You can use replicate or rep:

replicate(2, "my_string") # [1] "my_string" "my_string"  rep("my_string", 2) # [1] "my_string" "my_string" 

paste will put it together:

paste(replicate(2, "my_string"), collapse = "") # [1] "my_stringmy_string" 

Answer 2

With R 3.3.0, we can use strrep from base R

strrep("my_string",2) #[1] "my_stringmy_string" 

We can also pass a vector of values in times

strrep("my_string",1:3) #[1] "my_string"                   "my_stringmy_string"          #[3] "my_stringmy_stringmy_string"
