Here John, from the manual
URLs A note on file:// URLs. The most general form (from RFC1738) is file://host/path/to/file, but R only accepts the form with an empty host field referring to the local machine. This is then file:///path/to/file, where path/to/file is relative to /. So although the third slash is strictly part of the specification not part of the path, this can be regarded as a way to specify the file /path/to/file. It is not possible to specify a relative path using a file URL. No attempt is made to decode an encoded URL: call URLdecode if necessary. Note that https:// connections are not supported. So, when you use a https Url as opposed to a http url the former is not supported. You might try RCurl package getURL() which has support for HTTPS, provided your libcurl has support for SSL ( as I recall) On Thu, Jan 6, 2011 at 11:53 AM, John Kane <jrkrid...@yahoo.ca> wrote: > # Can anyone suggest why this works > > datafilename <- " > http://personality-project.org/r/datasets/maps.mixx.epi.bfi.data"; > person.data <- read.table(datafilename,header=TRUE) > > # but this does not? > > dd <- " > https://sites.google.com/site/jrkrideau/home/general-stores/trees.txt"; > treedata <- read.table(dd, header=TRUE) > > =================================================================== > > Error in file(file, "rt") : cannot open the connection > In addition: Warning message: > In file(file, "rt") : unsupported URL scheme > > # I can access both through a hyperlink in OOO Calc. t > # Thanks > > ______________________________________________ > R-help@r-project.org mailing list > https://stat.ethz.ch/mailman/listinfo/r-help > PLEASE do read the posting guide > http://www.R-project.org/posting-guide.html > and provide commented, minimal, self-contained, reproducible code. > [[alternative HTML version deleted]]
