| read.table.url {base} | R Documentation |
Extensions of read.table, scan,
source
and file.show to read text files on a remote HTTP (Web)
server.
read.table.url(url, port = 80, check.MIME.type = TRUE, ...)
scan.url(url, port = 80, check.MIME.type = TRUE, ...)
source.url(url, port = 80, check.MIME.type = TRUE, ...)
copy.url(url, port = 80, error.is.fatal = TRUE, file = tempfile(),
check.MIME.type = TRUE, drop.ctrl.z = TRUE)
url.show(url, port = 80, check.MIME.type = TRUE, file = tempfile(),
delete.file = TRUE, ...)
HTTP errors are handled correctly, but attempts to read non-text files
are currently not (thus the check.MIME.type option).
copy.url returns the name of a temporary file.
