Subject: [Rd] Windows download.file sometimes pauses / truncates large files
Message-ID: <4EA706A6.2080106@fhcrc.org>

With

C:\Users\User>R --version
R version 2.14.0 RC (2011-10-23 r57410)

Platform: x86_64-pc-mingw32/x64 (64-bit)

running

download.file('http://www.ebi.ac.uk/microarray-as/ae/files/E-TABM-25/E-TABM-25.raw.1.zip', 
tempfile())

sometimes gets 52% (according to the dialog box) of the way through, and 
then pauses or, when running R CMD check, truncates (see 
http://bioconductor.org/checkResults/devel/bioc-LATEST/ArrayExpress/moscato1-checksrc.html).

I tried options(internet.info=0, timeout=600), without effect; the 
messages from internet.info are the same on successful and failed downloads.

Thank you,

Martin
