Dear R helpers
Wish you all a very Happy and Prosperous New Year 2011.
I have following query.
country = c("US", "France", "UK", "NewZealand", "Germany", "Austria", "Italy",
"Canada")
Through some other R process, the result.csv file is generated as
result.csv
var1 var2 var3 var4
I had looked at that link, but it doesn't answer my question.
Here is the answer I got from StackOverflow:
options("HTTPUserAgent") or getOption("HTTPUserAgent") prints your
current settings, and options(HTTPUserAgent="My settings") is the way
to change it.

It is very interesting and a good way to plot,
