If you read the description of the destfile argument of download.file

destfile	A character string with the name where the downloaded file is saved. Tilde-expansion is performed.

the error in your code is that you specified a directory as destination. It must be a file: ""C:\\Users\\jones\\Desktop\\downloadedfile.kmz".

For the record: PLEASE do read the posting guide http://www.R-project.org/posting-guide.html
