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