[R] Writing and running a R program

[Subramanian Karthikeyan]

Is there a way I can combine multiple lines of R commands (see below) into
a little code snippet or a program in a text file, and run it in R to do my
analysis?

sink("mysink.txt")
for (......) {
code for creating a dataframe from supplied data
code for doing anova from selected data
}

Thanks very much.

Karth.
