Description
\datasetvariable{mydataset}{mytable}{myvariable}
This command retrieves the value of myvariable in the table mytable stored in the dataset mydataset. Two complete examples are shown below.
Usage
% Define a dataset called 'mysteries' \definedataset[mysteries] % The first anonymous table is stored at position 1, the second at position 2, etc. \setdataset[mysteries][assistant=Watson] % Retrieving an anonymous table \datasetvariable{mysteries}{1}{assistant} % Watson
or
% Define a dataset called 'mysteries' \definedataset[mysteries] % Store a key-value dataset called 'Doyle' \setdataset[mysteries][Doyle][detective=Holmes, assistant=Watson, officer=Lestrade] % Retrive the variable 'assistant' from the 'Doyle' table in the 'mysteries' dataset \datasetvariable{mysteries}{Doyle}{assistant} % Watson
