R help - Dec 2011 - incomplete final line found warning

Hi,

I saved the following as a UTF-8 encoded file named amberutil.r

as.factor.loop <- function(df, cols){

	if (!is.null(df) && !is.null(cols) && length(cols) > 0)
	{
		for(col in cols)
    {
			df[[col]] <- as.factor(df[[col]])
		}
	}
  df
}

And got this warning message,
> source('D:/ambertuil.r')
Warning message:
In readLines(file) : incomplete final line found on 'D:/ambertuil.r'

Can you help with this?

Regards,

Xiaobo Gu

Help with what? You got a warning. And it had information that should  
tell you how to edit the file if the warning bothers you.

A warning message such as this could not be clearer.
It means that the last line of the file does not end with a <newline>
sequence ==> the final line of the file is incomplete.

In an editor go to the end of that line and press <Enter> or
<Return>
And save.

Alternatively configure your editor to always terminate the last line of a
file with  a <newline> sequence.
