[R] Header of dataframe

[Benjamin Dickgiesser]

Hi
I am fairly new to R and I would appreciate some help to hopefully a
trivial problem.

I created a function:

summary.aggregate <- function(y, ...)
{
	temp.mean 	<- aggregate(y, FUN=mean, ...)
	temp.sd  		<- aggregate(y, FUN=sd, ...)
	temp.length <- aggregate(y, FUN=length, ...)
	temp <- data.frame(cbind(mean=temp.mean$x,stdev=temp.sd$x,n=temp.length$x))
}

this outputs e.g.:

      mean    stdev  n
1 645.6125 65.94129 60
2 655.2121 70.64094 60
3 633.3161 80.48620 60
4 650.3897 77.59191 60
5 630.4955 84.98888 60
6 656.2608 66.16100 60
7 666.1775 74.39796 60
8 663.1543 71.10769 60

Is there an easy way to add a column name to the first column?

Thank you,
Benjamin
