User Function Return Query and Insert into When it comes to writing functions that interact with databases, one common pattern is to retrieve data from a query and then perform some operation on that data. In this case, we’re looking at a function that takes an argument (in this example, taskID), uses that argument to query a table (table_foo), retrieves the relevant data, performs some operation on it, and then inserts that data into another table (table_bar).

Understanding Ordinal Variables and Reordering in R Shiny Introduction Ordinal variables are a type of categorical variable where the values have a natural order or ranking. For example, if we’re analyzing customer satisfaction ratings, the values might be “Poor”, “Fair”, “Good”, and “Excellent”. In such cases, the values don’t just represent categories but also imply an order. Reordering an ordinal variable involves rearranging its values according to a specific ordering. This can be useful in various applications, such as data visualization, statistical analysis, or machine learning modeling.
