How to set a custom library path for TIBCO Enterprise Runtime for R (TERR)
By design, the installed client's (TIBCO Spotfire Analyst or TIBCO Spotfire Desktop) point-and-click "Tools > TERR Tools > Package Management" feature installs CRAN packages in a library folder that it finds or creates under the current user's Windows profile. This is also true when the installed client is hosted on a Citrix XenApp server.
One way to provide custom library path is to put custom code into the Spotfire desktop client's "TERRprofile.site" file:
In a TERR Console session launched using "Tools > TERR Tools > Launch TERR Console", the following command will show the path where the placeholder "TERRprofile.site" file is located:
file.path(Sys.getenv("TERR_HOME"), "etc")Once you know the location of "TERRprofile.site" file you can modify it according the example. Below is a modified "TERRprofile.site" example script. You will need to define your own value for the script's 'CustomUserLibraryPath' object, when you test it in your environment.
# TERR_HOME/etc/TERRprofile.site # This file is sourced when TERR starts. cat('\nTERR_HOME/etc/TERRprofile.site\n') cat('\nThis file is sourced when TERR starts.\n') cat('\nRunning TERRprofile.site\n\n') CustomUserLibraryPath <- "C:/TERR/CustomUserLibraryTERR" cat('\nCustomUserLibraryPath\n') print(CustomUserLibraryPath) if(file.exists(CustomUserLibraryPath)) { cat('\nSys.setenv(TERR_LIBS_USER = CustomUserLibraryPath)\n') Sys.setenv(TERR_LIBS_USER = CustomUserLibraryPath) cat('\nSys.getenv("TERR_LIBS_USER")\n') print(Sys.getenv("TERR_LIBS_USER")) cat('\n.libPaths(Sys.getenv("TERR_LIBS_USER"))\n') print(.libPaths(Sys.getenv("TERR_LIBS_USER"))) } else { cat(paste('\nUnable to find this specified CustomUserLibraryPath: "', CustomUserLibraryPath, '"\n', sep = "")) } cat('\n.libPaths()\n') print(.libPaths()) cat('\nutils::installed.packages(lib = .libPaths()[1])[, "Version"]\n') print(utils::installed.packages(lib = .libPaths()[1])[, "Version"]) cat('\nFinished running TERRprofile.site\n\n')Please note, Both TERR and open-source R use a single slash ("/") as the path separator, even on Windows. (A single backslash ("\") will not work, because the backslash is used as the first character in two-character escape sequences, such as "\t" for a tab and "\n" for a newline.)
Is there a way to bundle several R packages into a Spotfire package (*.spk file) that can be deployed from Spotfire Server to make them available to all of our Spotfire Analyst desktop clients?
