Re: [R] URL error when trying to use help function in R [Sec: UNOFFICIAL]
Thanks for the feedback. Peter, I have forwarded your response to our ICT division to see if there is anything they can do. One potentially silly question: what would happen if I had the help files loaded locally on my PC - would the call then work? I'm wondering about the wisdom of creating a proper directory structure, empty apart from the help files, on my local PC.

Hi I had similar issue and it was solved by setting proxy in browser preferences to do not use proxy server for 127.0.0.1 and it helped.

[R] URL error when trying to use help function in R [Sec: UNOFFICIAL]
Greetings, I am using R version 2.11.1 on a Dell computer, via a VMware connection to a remote server. My browser version is IE 8.0.6001.18702 and the OS is some corporate version of Microsoft XP. I'm trying to learn more about the tapply function , so I typed ?tapply into the command line. This opened up a browser window with url http://127.0.0.1:28138/library/base/html/tapply.html which is giving me an error message. I receive the same problem when trying for help on other commands, e.g. ?table http://127.0.0.1:28138/library/base/html/table.html and ?log http://127.0.0.1:28138/library/base/html/Log.html I did a whois on 127.0.0.1 via www.geektools.comhttp://www.geektools.com and got the information boxed below, which suggests I'm not going where I am supposed to be going when I ask for help. I'm assuming this problem is associated with my VMware link to the server. Is anyone else running this type of connection through to R and, if so, could they please advise how to remove the issue? I've been able to bring in my data table fine, and do some commands on it, the issue so far appears related only to help files. I'm assuming this is because the help files call a URL that, in my case, appears to be incorrect (whereas the R commands are not calling a URL and therefore are working fine).
