[R] Reading and writing data

Hi All,

Two quick questions.

1) I am using write.table to output data.frames to ascii files, e.g., 

test <- data.frame(rnorm(2))

"1" -0.718560808193286
"2" -1.07965693020656

Is it possible to output the data without the first column, i.e.,


2) Is there a simple way to read in data and skip lines, i.e., say skip every 
second line. I could use ``scan'' to read in the data and use a "for" loop to 
perform the skipping in R. However, I am wondering is there a one-step method.

Thanks in advance,
