This isn't a R-Devel related question, it would have been better sent to R-Help:

https://stat.ethz.ch/mailman/listinfo/r-help

Also, you are asked to read the docs for the functions you are having problems with. The answer is in ?write.csv and the argument row.names. Setting this to FALSE gives you your desired behaviour, e.g.:

> ?write.csv
> data(iris) #example data
> write.csv(iris, row.names = FALSE)
> write.csv(iris, row.names = TRUE)

As I didn't specify a filename as the file argument, the results are displayed at the console.
