I am trying to install this next map generation package but is giving the following error

install.Packages("maptools",Dep=TRUE) Installing package into C:/Users/rafael/Documents/R/win-library/3.0' (as ːlib' is unspecified) --- Please select a CRAN mirror for use in this Session ---- Warning: Unable to access index for Repository http://cran-r.c3sl.ufpr.br/bin/windows/contrib/3.0 Warning: Unable to access index for Repository http://www.stats.ox.ac.uk/pub/RWin/bin/windows/contrib/3.0 Lost warning messages are: 1: In open.Connection(con, "r") : 'Cran.r-project.org' could not be connected to port 80. 2: package ːmaptools' is not available (for R version 3.0.2)

Can anyone tell me how to handle ?

    Give more information about your session (R version, Operating System etc.). Anyway, I would try another repository and check the internet.

    As you can see here (http://cran.r-project.org/web/packages/maptools/index.html) maptools is available for any version of R higher than R 2.10. I believe it may be a problem in your connection or in that particular repository.

    Rafael, is this a work computer? It seems that access to the CRAN mirrors have been blocked.

  • Yes and the computer of my internship ! I tried with ADM login but not the right one !

  • I am on Windows 7 version of R 3.0.3 64 bits

  • I can’t update existing packages either

  • Rafael, it is a network problem that you are using, you will have to see this with the IT area of your internship.

Rafael, if you are using the Rstudio just specify the path there where I put the red arrow and then install by typing the package name there in Packages.

If you specify by menu you can install via install.packages("maptools").

    It only worked in R Studio but I have version incompatibility, I’ll update it and see what !
