Hi,
> url <- "ftp://ftp.ncbi.nlm.nih.gov/genomes/ASSEMBLY_REPORTS/All/GCF_000001405.13.assembly.txt"
> download.file(url, tempfile())
trying URL 'ftp://ftp.ncbi.nlm.nih.gov/genomes/ASSEMBLY_REPORTS/All/GCF_000001405.13.assembly.txt'
Error in download.file(url, tempfile()) :
cannot open URL 'ftp://ftp.ncbi.nlm.nih.gov/genomes/ASSEMBLY_REPORTS/All/GCF_000001405.13.assembly.txt'
In addition: Warning message:
In download.file(url, tempfile()) : InternetOpenUrl failed: ''
If I set method="curl" it works fine. This was on R-3.2.2-beta (sessionInfo() below) but I got the same results in R-3.2.1 and R-devel.
This does not happen on Windows Server 2008 but it happens on Windows Server 2012.
