I tried to extracting data from server and the system gives me the following message,
"Error in UseMethod(“open”) :
no applicable method for ‘open’ applied to an object of class “data.frame”
In addition: Warning messages:
I checked getDbcohortData function and found there is one line(line 135) code which is not recognized by R
"open(result$cohorts) " what do developers wanner to do.? R don’t have open function.
thanks
