Thanks for the response. I am currently using Windows 7. I tried the
following command:
install.packages("XML", repos =
"http://www.omegahat.org/R")
and I got:
Installing package into ?C:/Users/Bob/Documents/R/win-library/3.1?
(as ?lib? is unspecified)
Warning: unable to access index for repository
http://www.omegahat.org/R/bin/windows/contrib/3.1
package ?XML? is available as a source package but not as a binary
Warning message: package ?XML? is not available (for R version 3.1.2)
I also tried this command:
install.packages("RSXML", repos =
"http://www.omegahat.org/R")
and I got:
Installing package into ?C:/Users/Bob/Documents/R/win-library/3.1?
(as ?lib? is unspecified)
Warning: unable to access index for repository
http://www.omegahat.org/R/bin/windows/contrib/3.1
Warning message:
package ?RSXML? is not available (for R version 3.1.2)
I am wondering why it is not work. Please help.
Thanks
Bob
