Question 1

How do I filter data in Gota with a custom condition?

Accepted Answer

Use the Filter method with series.CompFunc and a user-defined function that returns a bool. For example, to filter strings with a prefix, define a function like hasPrefix and pass it to Filter, as shown in the README's custom comparator section.

Question 2

Gota vs pandas: which should I use for data wrangling?

Accepted Answer

Gota is best for Go-native applications where type safety and integration with Go code are priorities, but pandas in Python offers a more mature ecosystem with advanced analytics and visualization tools. Choose Gota if you're committed to Go, otherwise pandas is more feature-rich.

Question 3

Can Gota handle missing values or NaN in datasets?

Accepted Answer

Yes, Gota supports missing values in Series and DataFrames, allowing operations on datasets with non-measurements. It handles NaN elements similar to pandas, maintaining column type integrity during manipulations.

Question 4

How do I join two DataFrames in Gota?

Accepted Answer

Use the Join methods like InnerJoin, LeftJoin, RightJoin, or CrossJoin, specifying the key columns. For instance, df.InnerJoin(df2, "D") joins on column D, as demonstrated in the README with examples for different join types.

Question 5

Is Gota production-ready for building data pipelines?

Accepted Answer

Due to the unstable API warning, it's risky for critical production systems. It's suitable for experimental tools or internal pipelines where you can manage updates, but ensure thorough testing and version locking to avoid breaking changes.

Question 6

How to convert a Gota DataFrame to a gonum matrix?

Accepted Answer

Implement the matrix interface by defining At and T methods that use the DataFrame's Elem method. The README provides an example struct and methods, such as creating a wrapper that calls Float() on elements for conversion.
