Dear Kate, I cannot find your small script, but I downloaded the file using your command line. It has the size of 142773760 bytes (136.2 MB). Hth, Albrecht -- Albrecht Kauffmann alkauffm at fastmail.fm Am Do, 6. Dez 2018, um 13:45, schrieb Kate Stone:
Hello r-help,
Could you help me determine whether this is an R bug or not?
I've been trying to read this binary file in R:
download.file("
ftp://ftp.fieldtriptoolbox.org/pub/fieldtrip/tutorial/preprocessing_erp/s04.eeg ","s04.eeg")
and I get a different length file (i.e. much longer) in Windows >= 8 x64 (build 9200) than in Ubuntu. I've tested it with different R versions in Windows and different package versions with the same incorrect result. Other colleagues have tested it on the same Windows/Ubuntu builds and got the correct length. I'm not sure whether this is an R problem or something to do with my OS specifically, or even with the file itself. Any ideas?? I've attached a small script demonstrating the issue.
