Installing
tnet is an extension package to R that can be downloaded using the CRAN-servers. There are three steps to get tnet up and running:
1: Installing R
R is an open-source package that can be compiled on the vast majority of platforms. There are also pre-compiled versions for Windows (both Win32 and x64), Mac OS X (release 10.5 and above), and Debian, Redhat, Suse, and Ubuntu Linux. To get the source code or the pre-compiled versions, you need to go to www.r-project.org, click on CRAN under Download on the right, select a server close to you, select your operating system (e.g., Windows), click on base, and then click on Download R on the top of the page. Then you need to follow the installation instructions on your screen.
If you are using Windows on a fairly new computer, you might have a 64-bit version of Windows installed instead of the ‘old’ 32-bit version. You can find out which version you have by right-clicking on Computer/My Computer on the Start menu, and selecting Properties. If you have the 64-bit version of Windows installed, I would recommend that you install the 64-bit version of R as more memory will then be available.
For more information, see the R-website.
2: Installing tnet
The standard command for installing packages in R is install.packages(). To install tnet using this command, you would simply type install.packages("tnet") and then select a server close to you.
If you are using the Windows version of R, you should be able to install tnet by going to the ‘Package’-menu, opening ‘Install package(s)’, selecting a server close to you, and then, choosing ‘tnet’ from the list.
Updating tnet
tnet is in constant development. If you have installed extension packages, I would recomment that you run update.packages() once in a while to get the lastest version of the installed packages. This command will update any of the extension packages that you might have on your system if a new version is available, including tnet.
3: Loading tnet
The functions within an installed package is not available unless the package is specifically loaded. Everytime a new session (i.e., a window) is opened, the required packages for that session need to be loaded. This is done using a function called library. As shown in the code examples, tnet is loaded by typing library(tnet) in R.

Hi
it seems R version 2.14.0 doesn’t support tnet, right?
I was trying to install tnet and got this warning message
“In getDependencies(pkgs, dependencies, available, lib) : package ‘tnet’ is not available (for R version 2.14.0)”
Look forward to hear from you
Thanks so much

Sorry, it works.
The problem was that I should have set proxy in R (using setInternet2(TRUE) ).

Hello,
thank you very much for this blog. I have the same problem of Alireza, but I don’t know how it fixed.
“In getDependencies(pkgs, dependencies, available, lib) : package ‘tnet’ is not available”
Best regards

Hi Fabian,
Please try to download the package, and the dependencies, manually and install using those files. This is probably an issue with the connection to the CRAN servers.
Best,
Tore

Thank you for your quick response, but from where can I download manually the tnet package? Apparently it isn’t on the CRAN servers.
Best regards, and thank you very much

Hi Junyan,
First you need R. Then you can simply type install.packages(“tnet”) in R.

Hi Tore, I haved installed package from local zip files(including igraph and survival).However,after I typed ” library(tnet) “,it said as follows:
Loading required package: igraph
Error in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]) :

Hi Yimmy,
That is an igraph issue. Please reach out to them directly.
