参数:repository
Where to look for data. The default value is the location of the complete bacterial genome sequences at ncbi ftp repository.
到哪里找数据。默认值是完整的细菌基因组序列在NCBI FTP库的位置。
值----------Value----------
Returns a data frame which contains the following columns:
返回的数据框包含以下几列:
参数:species
The species name as given by the corresponding folder name in the repository (e.g. Yersinia\_pestis\_KIM).
的种名给予相应的库中的文件夹名称(如耶尔森氏菌\ _pestis \ _KIM)。
参数:accession
The accession number as given by the common prefix of file names in the repository (e.g. NC\_004088).
加入给出的公共前缀库中的文件名(如NC \ _004088)。
参数:size.bp
The size of the sequence in bp (e.g. 4600755).
的碱基序列(例如,4600755)的大小。
参数:type
A factor with two levels (plasmid or chromosome) temptatively deduced from the description of the sequence.
有两个水平的一个因素(质粒或染色体)temptatively推导出的序列的描述。
警告----------WARNING ----------
This function is highly dependant on ncbi ftp site conventions for which we have no control. The ftp connection apparently does not work when there is a proxy, this problem is circumvented here in a rather crude way.
此功能是高度依赖于NCBI ftp站点公约是我们无法控制的。 FTP连接的显然不工作时,有一个代理,这个问题是预防性的,在这里的一个相当粗浅的方式。
