使用getSRAdbFile（）會產生sqlite錯誤

我正在使用Bioconductor的SRAdb軟件包。不幸的是，當試圖下載SRAdb時，我遇到了sqliteSendQuery中的一個錯誤（見下文）。使用getSRAdbFile（）會產生sqlite錯誤

有人建議安裝最新的sqlite3版本。但問題依然存在。

sqlFile <- getSRAdbFile()

我覺得有什麼毛病getSRAdbFile()。它看起來像文件無法正常下載：

0K .              100% 208M=0s 

2016-04-27 16:08:52 (208 MB/s) - ‘SRAmetadb.sqlite.gz’ saved [1513/1513]

我得到的東西通過下載使用相同的URL（http://dl.dropbox.com/u/51653511/SRAmetadb.sqlite.gz）的文件，用wget，與gzip解壓縮，然後從開始像正常的連接工作在R內。

要保留在R內的所有內容，您可以使用system2或download.file與R.utils::gunzip。
