Problems with persist-results.R

After running all the chain with absolutely no errors and when I go to data > explorer tab in the app I find that the variables I created on the chain do actually exist (for example density, basal area, etc.) but they are completely empty. It happens the same when I export the data to an excel file. Anyone experienced something similar? Bests

Dear Juak,

can you please check in RStudio project that 1) you have given the area scripts in the /sampling folder, and that 2) none of the result attributes is containing just NAs. If any of variables in your chain contains only NAs, then persists-results.R fails. Also 3) after running system/calculate-results.R, that "per hectare" result variables are ok, (i.e., if in your chain you have tree$tree_basal_area, there will be a new variable tree$tree_basal_area_ha)

I just test one of my chains and persists-results.R worked. If the problem gets not solved, please contact us again so we can look at your case in detail.

Hi Lauri,

thanks for your fast reply. I answer to your question one by one:

area scripts are there
there are some variables with some NAs but no variable contains only NAs
in my entity tree (example) when I check it on R I obtain satisfactory results in the variable called tree$basal__area__ha

My problem is that in R everything looks nice and when I run persist-results.R everything goes smooth but then nothing gets into my survey back in Arena.

Best regards, Jokin

Hi Jokin, try to replace all remaining NAs with 0.

Hi Lauri, I cleaned all the tables generated in R, example (treeResults) and no NAs are found there... I don't know what else to do.
