Hi All,
I just tried Firefox that David referred and found it can also
return the
correct result as Google Chrome.
So now it is more clear now that readLines() function uses IE as the
default explorer, so it return the wrong result. Then the possible
solutions are,
1. Could we change the options in readLines() to set another
explorer as
the default explore, e.g. Google Chrome?
?options # and look at the HTTPUserAgent choice
I believe this:
> options()$HTTPUserAgent
[1] "R (2.14.0 x86_64-apple-darwin9.8.0 x86_64 darwin9.8.0)"
... is telling me that the choice is passed off to the OS, and only
because you keep referring to (MS)IE do we know that you are running
one of that Redmond company's products. (You should evidently do more
study of the relationship of R to the OS platform you use.)
2. Could it be possible to set IE explorer in a rational way, so
that it
can return the same results as Google Chrome and Firefox? I have
tried to
modify the encoding method in IE, but it doesnot work.
Any suggestions or help?
That is not an appropriate question for this mailing list. You persist
in posting in HTML. Maybe you should also spend more time learning to
use you mail client correctly?

Hi All,
I met a problem using readLines function to return the data from
Google
maps.
readLines(url("
http://ditu.google.cn/maps/geo?q=+qianshuichong,+guichi+anhui,+CN&output=csv&key=ABQIAAAAq8Fnd_oUka-7RdS6BrD7GBTqeABoQuNTXS36G_rkiwQnKRW6GBTkns8JpKz6y6dScgB8827dlddUlg
"),
n=1, warn=FALSE)
[1] "200,4,30.6528380,117.4872250"
The above code is ok because the address is English, but it cannot
work
when i change the address into zh-hans (Chinese simplified). See
below.
readLines(url("http://ditu.google.cn/maps/geo?q=+Ç°Ë®³å<http://ditu.google.cn/maps/geo?q=+%E5%89%8D%E6%B0%B4%E5%86%B2

&language=zh-CN®ion=zh_Hans"),
n=1, warn=FALSE)
[1] "400,0,0,0"
The returned value is wrong. I also tried several other options, but
still have the same problem. The interesting thing is if i paste
the URL
into the IE explorer directly, it do return the correct values.
Anybody can give me some suggestions or hints to solve this?
Thanks a lot.
P.S. See below for the other possibilities i tried.
