I’ve run the Keppra and Angioedema study on my local database and it worked perfectly. Just curious if anyone tried Keppra study on the SynPuf data. I always have the problem during the step of normalizing covariates. Is that a problem related to the Synpuf data structure?
here is the code:
Normalizing covariates
Error in if (nrow(covariates) == 0) { : argument is of length zero
In addition: Warning messages:
1: In lowLevelQuerySql.ffdf(connection, sql) :
Data has zero rows, returning an empty data frame
2: In FeatureExtraction::getDbCovariateData(connection = connection, :
No data found
