R Project: How to install packages when server is not connected to the internet.

[krwinters11]

I have a server that is not connected to the internet. I need to install packages on my R Project app on the server. I have moved them into the library (downloaded them on another computer), but the app in splunk doesn't recognize them. Any tricks to this? Regards.

At the moment, that is not supported by the app.

However, when executing R as part of a Splunk search, the default R library (the folder where additional packages are installed to) is not used. The actual library path is depends on your OS and version.

I added an Issue on R Project GitHub page and already implemented some code.

Before publishing a new version, I would like to test the changes with some packages. Which package are you trying to install?

We are trying to install forecast. Thank you for your help

I just tried installing the forecast without internet access from the Splunk server.

To do that, I installed the latest version of the R app which allows "uploading" packages (downloaded from CRAN).

So I downloaded the forecast package from CRAN an uploaded it to the R app and triggered installing all not yet installed packages using the R search command from within the search app.

That gave me an error message saying it's missing another package. After uploading that, it said it missing another package and so on ... at the end it found out that the forecast package depends on the following packages:

zoo
timeDate
tseries
quadprog
fracdiff
Rcpp
colorspace

After downloading each of them from CRAN and uploading each to the R app, the installation of the forecast package worked (without having internet access from the Splunk server).

I am getting this error when clicking the "Install now" button:
Cannot install package 'zoo'. Unable to install package 'zoo': Warning in unzip(zipname, exdir = dest) : internal error in 'unz' code
Warning in read.dcf(file.path(pkgname, "DESCRIPTION"), c("Package", "Type")) :
cannot open compressed file 'zoo/DESCRIPTION', probable reason 'No such file or directory'
Error in read.dcf(file.path(pkgname, "DESCRIPTION"), c("Package", "Type")) :
cannot open the connection

I need to upload the zip file, correct?

[rfujara_splunk]

Correct, just upload all of the packages: forecast plus the other 7 packages I mentioned above. Then click on the "Samples" page to trigger installation of each of them.

[krwinters11]

I don't have a "Samples" page. I clicked the "Install now" button on the "Packages" page. After I click that button though, it says "Installation Error" beside the package. It has done this for all the packages I have tried. Any ideas?

and I get this error when I try to run a search out of the examples page:

command="r", Cannot install package 'colorspace'. Unable to install package 'colorspace': Warning in unzip(zipname, exdir = dest) : internal error in 'unz' code Warning in read.dcf(file.path(pkgname, "DESCRIPTION"), c("Package", "Type")) : cannot open compressed file 'colorspace/DESCRIPTION', probable reason 'No such file or directory' Error in read.dcf(file.path(pkgname, "DESCRIPTION"), c("Package", "Type")) : cannot open the connection

[krwinters11]

I have the DESCRIPTION file, so I'm not sure why it isn't working. It seems like it is so straight forward, I don't know what is wrong. thank you for your help!

[rfujara_splunk]

That sounds bad. If you want we can do a WebEx session. If you are interested, let's schedule a time by email (rfujara@splunk.com).

[krwinters11]

That would be great. I sent an email.
