Patient level prediction Package no connection

Developers
#1

Hi all,

I developed a Targeted and Outcome cohort using Atlas. I followed the instructions to customize the R-package but I receive every time an error while I can successfully build the package. For example, in the CodeToRun.R function I receive an error that there is no file called “setting.csv” if I want the argument createShiny = T in the function execute. If I leave createShiny = F and follow the instructions in the readme.md file I receive the error that the connection (org.postgresql.util.PSQLException) failed. However, I can access the database with my credentials in Jupyter Notebook.

I feel like I am missing something and I hope someone can help me.

Thank you in advance!

BTW, this is specified in my logs.txt

Hi, It seems to be because the shiny data folder is not created. Would you like to change the populateShinyApp.R code as shown below and rebuild it?

And - do you get an error when running the “PatientLevelPrediction::viewMultiplePlp(outputFolder)” code with createShiny = F? It can show the model results with this function whether or not doing the createShiny function.

Hi,

Thank you for your fast reply! Unfortunately, this does not work properly.
If I do createShiny = T, the error is that there is no write permission for directory.
If I do cheateShiny = F, the error is “Error in checkPlpInput(result) : Incorrect class for input result”

I am running the package on my own computer, so rights and permissions shouldn’t be an issue.

I hope you have another possibility to solve this issue.

Attached is the log,

I think the issue is using a relative path rather than absolute (e.g., ‘./myfolder’) - make the path absolute and I think it will work
