I'm looking to download a gzipped csv and load it as an R object without saving it first to disk. I can do this with zipped files but can't seem to get it to work with `gzfile` or `gzcon`. 

Example: 

```
grabRemote <- function(url) {
    temp <- tempfile()
    download.file(url, temp)
    aap.file <- read.csv(gzfile(temp), as.is = TRUE)
    unlink(temp)
    return(aap.file)
}
grabRemote("http://dumps.wikimedia.org/other/articlefeedback/aa_combined-20110321.csv.gz")

```

That downloads a (small) gz compressed file containing [Wikipedia article feedback data](http://www.mediawiki.org/wiki/Article_feedback/Data) (not important, but just to indicate it isn't giant or nefarious). 

The code I have works fine but I feel like I'm missing something very obvious by resorting to creating and destroying a temporary file.
