The authors of the spi package are clearly coming from some other programming language, and did some un-Rish things.
Where you are assuming that nargs, the first argument, is the number of months, in fact it is literally the number of arguments you're passing to the function, not counting itself, and so must be in the range 3-7. So you actually need: spi(3,"tercanspi.txt",1966,2017) spi(7,"tercanspi.txt",1966,2017,"Tercan Standart Yağış İndeksi",2,"Yıllar","Aylar") spi(7,"tercanspi.txt",1966,2017,"Tercan Standart Yağış İndeksi",2,"Yıllar","Aylar") spi(7,"tercanspi.txt",1966,2017,"Tercan Standart Yağış İndeksi",2,"Yıllar","Aylar") No matter what the help implies, you apparently can't choose your own timescale. I think you might have more success with the SPEI package, on CRAN, which includes both SPEI and SPI.
