R help - Sep 2009 - Problem with downloading workspace file from a web address

Dear All,

To load a previously saved workspace, one can do the following:

load("/path/to/the/saved/workspace/file")

However, if the path to the saved workspace file is a web address, one
gets the following error:

?Error in readChar(con, 5L, useBytes = TRUE) : cannot open the connection
In addition: Warning message:
In readChar(con, 5L, useBytes = TRUE) :
  cannot open compressed file
'http://phhs80.googlepages.com/workspace20090922', probable reason
'No
such file or directory'?

To circumvent this problem, one can download the saved workspace file
to a local folder with download.file() and the option

mode="wb"

active.

My question is: Should not load() have the same mode option so that
everything could be done only with load() (and not with two
instructions: downaload.file() and load())?

Thanks in advance,

Paul

How did you try?

Does load(url("http://phhs80.googlepages.com/workspace20090922")) work
for you?
