老师您好！我用你们提供代码在GDC里面下载数据时候出现错误，错误代码如下：

GDCdownload(query = query,

+             directory = DataDirectory,files.per.chunk=6, method='client')

Downloading data for project TCGA-CHOL

试开URL’https://gdc.cancer.gov/files/public/file/gdc-client_v1.6.0_Windows_x64-py3.7_0.zip'

Content type 'application/zip' length 16207515 bytes (15.5 MB)

Error in unzip(basename(bin)) : zip名字参数不对

此外: Warning message:

In if (grepl("^https?://", url)) { : 条件的长度大于一，因此只能用其第一元素
