I have been trying the r_exec function and met the following problem:
When all the attributes of the array are of data type "double", then there is no problem; However, if not all the attributes are of datatype "double", even if I only use the attribute with type "double", I still got the following error:
Error in scidbquery(query, afl, async = FALSE, save = "lcsv+", release = 0, :
SystemException in file: LogicalRExec.cpp function: checkInputAttributes line: 51
Error id: scidb::SCIDB_SE_OPERATOR::SCIDB_LE_ILLEGAL_OPERATION
Error description: Operator error. Illegal operation: r_exec only accepts an input with attributes of type double.
My experimental array (t5) has the following schema:
1 0 t5 [i=1:8,2,0,j=1:8,2,0]
the code is like this:
Are there any way of solving this problem?
Thanks a lot,
