Create a character string that contains values from R objects. (The sprintf is much more robust than is touched on here, but this will provide sufficient info for a basic start.)
- fmt – A character string with some occurrences of %s, which will be places that object values are inserted.
- … – The R objects to be inserted. The number of items should correspond to the number of %s occurrences in fmt.
Example. Below are two simple examples of using sprintf.
> > x <- 2349 > sprintf("Substitute in a string or number: %s", x)  "Substitute in a string or number: 2349" > > sprintf("Can have multiple %s occurrences %s", x, "- got it?")  "Can have multiple 2349 occurrences - got it?" >
