Following up my lattest posting on how to download files from the cloud with R..

dl_from_GoogleD <- function(output, key, format) {

## Arguments:
## output = output file name
## key = Google document key
## format = output format (pdf, rtf, doc, txt..)
## Note: File must be shareable!

require(RCurl)
bin <- getBinaryURL(paste0("https://docs.google.com/document/d/", key, "/export?format=", format),
ssl.verifypeer = FALSE)
con <- file(output, open = "wb")
writeBin(bin, con)
close(con)
message(noquote(paste(output, "read into", getwd())))
}


# Example:
dl_from_GoogleD(output = "dl_test.pdf",
key = "1DdauvkcVm5XtRBkQIv1na8PeLAwpCBdW8pALCFpRWeM",
format = "pdf")
shell.exec("dl_test.pdf")
