TERR: 'there is no package called 'WeibullR'' error while the package is installed
TIBCO Spotfire®

Hi all,

In a report we're using TERR to do Weibull analyses. My colleage built the report and it works fine on her computer.

On my computer however I'm facing an issue I can't make sense of. I receive the 'there is no package called 'WeibullR'' error (see figure 1) while the package is installed (see figure 2).

What's happening here and how can it be solved?



Figure 1

Figure 2


My colleage told me that normally the WeibullR package is identified, but that the problem occurs when this package is called within an RGraph function like this:

AllDataplot <- RGraph(
            xlim=c(1,1e12),main="All Data")
      packages="WeibullR",data = c("DfFailN","DfSusN"))


SInce the error comes from a call to RinR::RGraph, it sounds like your copy of R (not TERR) doesn't have the package installed.  FIre up R, install the package on it, and see if the problem goes away.  If you don't know which copy of R on your system TERR is calling, you can use RinR::REvaluate(R.home()) to find out.

Thanks for your comment. We are not using a remote TERR engine, the report is set to use the local TERR engine.

Is it possible that Spotfire is using a remote TERR engine to run data functions but the local TERR for the console?  You can check this out by running the following script in both contexts:

output <- capture.output({
    cat("version=", version$version.string, "\n")
    cat("R.home()=", R.home(), "\n")
    cat("HOSTNAME=", Sys.getenv("HOSTNAME"), "\n")
    cat("COMPUTERNAME=", Sys.getenv("COMPUTERNAME"), "\n")
    cat("installed packages=", rownames(installed.packages()), "\n")

For the data function containing this script, make 'output' a data table output (there are no inputs) and  view it in a table visualization.  For the console test, follow the script with cat(output, sep="\n").  Do you see any differences between the data function's output and the console's output?
