Well, this is frankly an unsatisfactory answer, as it does not try to deal properly with the issues that you experienced, which I also did. However, it's simple and works. As this is a small text file, simply copy it in your browser to the clipboard, and then use: thefile <- read.table(text = "", h

That looks like a UTF-16LE byte order mark. Simply open the connection with the proper encoding: read.delim( 'https://online.stat.psu.edu/onlinecourses/sites/stat501/files/ch15/employee.txt', fileEncoding = "UTF-16LE" ) On Sat, Sep 7, 2024 at 3:57 PM Christofer Bogaso wrote: > > Hi, > >

Ha, the proper answer! Thanks for this, Iris. I followed up by consulting the Wikipedia "byte order mark" entry and learned something I knew nothing about. FWIW, if I had simply searched on t it would have immediately led me to BOMs. Best, Bert On Sat, Sep 7, 2024 at 1:30 PM Iris Simmons wrote:

Add the fileEncoding = "UTF-16" argument to the read call. For a human explanation of why this is going on I recommend [1]. For a more R-related take, try [2]. For reference, I downloaded your file and used the "file" command line program typically available on Linux (and possibly MacOSX)

When you specify LE in the encoding type, you are logically telling the decoder that you know the two-byte pairs are in little-endian order... which could override whatever the byte-order-mark was indicating. If the BOM indicated big-endian then the file decoding would break. If there is a BOM,

I tried it on R 4.4.1 on Linux Mint 21.3 just before I posted it, and I just tried it on R 3.4.2 on Ubuntu 16.04 and R 4.3.2 on Windows 11 just now and it works on all of them. I don't have a big-endian machine to test on, but the Unicode spec says to honor the BOM and if there isn't one to ass
