[R] SPI package error

[arun]

HI Catalin,

This seems to work:

spi(6,"spi.txt",1963,2010,"Standardized Precipitation Index - Rio Grande do Norte State",2,"years","months")

From the source code:




spi #on your R console
---------------------------

 if (nargs < 3) {
        return("Error: very small number of arguments")
    }
    else {
        if (nargs > 7) {
            return("Error: very large number of arguments")
        }


#It also requires 

 else {
            tit = paste(title, sep = "")
        }


------------------------

when I try:

spi(7,"spi.txt",1963,2010)
#Error in paste(title, sep = "") : 
 # argument "title" is missing, with no default
 spi(2,"spi.txt",1963,2010)
#[1] "Error: very small number of arguments"
 spi(12,"spi.txt",1963,2010)
#[1] "Error: very large number of arguments"




I think it would be better to contact the package maintainer regarding this:
maintainer("spi")
#[1] "Josemir Neves <josemir.neves at gmail.com>"


A.K.

Thanks for help!
the reproducible example is>
data(spi_data)
write.table(spi_data,file="spi.txt",quote=FALSE,row.names=TRUE)
## Standard format with the output in the text format
spi(6,"spi.txt",1963,2010)
