Good morning all, I am running linux on Ubuntus. I am unable to install any R packages. The error message below always returns whenever I make an attempt:
> install.packages("cvt") Warning in install.packages("cvt") : argument 'lib' is missing: using '/home/ogbos/R/i486-pc-linux- gnu-library/2.8' --- Please select a CRAN mirror for use in this session --- Loading Tcl/Tk interface ... done Warning: unable to access index for repository http://cran.za.r-project.org/src/contrib Warning messages: 1: In open.connection(con, "r") : unable to connect to 'cran.r-project.org' on port 80. 2: In install.packages("cvt") : package cvt is not available It does appear that this has to do with internet connection. I entered ping cran.r-project.org on the command line expecting to see: 'PING cran.wu-wien.ac.at (137.208.57.37) 56(84) bytes of data. 64 bytes from cran.wu-wien.ac.at (137.208.57.37): icmp_seq=1 ttl=46 time=141 ms 64 bytes from cran.wu-wien.ac.at (137.208.57.37): icmp_seq=2 ttl=46 time=142 ms 64 bytes from cran.wu-wien.ac.at (137.208.57.37): icmp_seq=3 ttl=46 time=141 ms' But I only saw PING cran.wu-wien.ac.at (137.208.57.37) 56(84) bytes of data. I also tried ping cran.za.r-project.org. The result only show: 'PING vhost.ru.ac.za (146.231.129.7) 56(84) bytes of data.' I do not know what else to do as I am but a new student of R. I will please appreciate any help. Thank you Ogbos [[alternative HTML version deleted]]
