How to not use first observation as column names in R?

Question

I have some data files without column headings and every time I import them into the workspace R will read the first observation as variable names. Is there any way to prevent R from doing this?

Answer 1

In read.table the option header=FALSE will not read the first observation as variable name.

Example:

write.csv(iris, "temp.csv")
read.table("temp.csv", sep=",", header=FALSE)

Works for read.csv(..., header=FALSE) too.
