How to install r2pmml from zip file? #14

Closed sjain777 closed 7 years ago

sjain777 commented 7 years ago

Hi, I need to install all packages from command line via exe/zip files existing on my machine. I see r2pmml-master.zip is available for download. But doing the following does not install it:

Rscript.exe -e "install.packages('r2pmml-master.zip', repos = NULL)"

Can you please let me know the fix? Thanks, Supriya

This r2pmml-master.zip ZIP file is automatically created by GitHub.

Looks like it's simply the zipped contents of the latest commit. Install it exactly the same as you would install any other R package from its ZIP source distributable:

unzip -q r2pmml-master.zip
cd r2pmml-master/
R CMD INSTALL .

Please note that there's a dot character (.) at the end of the R CMD INSTALL . command!

Hi, thanks for your prompt reply. I tried the above. But the library gets installed as r2pmml-master inside of R\R3.3.3\library. Upon invoking it inside of an R session as follows: library("r2pmml-master") I get error that no such library exists. Is this due to the name of the zip file being r2pmml-master instead of r2pmml? Just by changing the name of the zip file did not work either. Your help in resolving this would be greatly appreciated! Thanks.

Did you enter the r2pmml-master directory BEFORE executing the R CMD INSTALL . command?

The name of the installed package is retrieved from the /DESCRIPTION file. So, it doesn't matter what your working directory is called, the r2pmml package will be always installed as "r2pmml".

As pointed out earlier, this is a standard procedure for installing R packages from (ZIP-) source distributables. If you need any help, just search the web using pharses such as "how to install R package from (ZIP-) source".

Thanks for explaining why one needed to cd to r2pmml-master. The problem was after unzipping, the source code and DESCRIPTION files landed in r2pmml-master\r2pmml-master. So I had to do: cd r2pmml-master\r2pmml-master for the installation command to work. Thanks much for your help in having this problem resolved!

The source code and DESCRIPTION files landed in r2pmml-master\r2pmml-master

To summarize, we are using different un-zip tools on different operating systems. I'm using command-line zip utility on GNU/Linux. When unzipping the r2pmml-master.zip file, it creates a shallow directory structure (the package information file is located at r2pmml-master/DESCRIPTION).

You're using some other un-zip tool, which creates an extra directory layer that corresponds to the name of the ZIP file (the package information file is located at <zip-file-name>/r2pmml-master/DESCRIPTION).
