TL;DR
The return type of func readFile(fileName string) should be *dataframe.DataFrame.

Reasoning
You use the imports.LoadFromCSV(...) function to load your CSV file and want to return the resulting data frame. The API documentation of the github.com/rocketlaunchr/dataframe-go reveals, that LoadFromCSV function a pointer to your dataframe: *dataframe.DataFrame.

See documentation here documentation of LoadFromCSV:

func LoadFromCSV(ctx context.Context, r io.ReadSeeker, options ...CSVLoadOptions) (*dataframe.DataFrame, error)\

LoadFromCSV will load data from a csv file.

QUESTION

dataframe-go: How to filter using < > operators?

Asked 2020-Apr-20 at 19:22

I'm trying to do a simple filter in dataframe-go. I adapted from the Github example and tried to use a simple > operator in the Filter Function, but the compiler gave invalid operation: vals["day"] > 4 (operator > not defined on interface) error (see my code below)

Ok, so I changed the type to map[string]int64 but then, it gave the error: cannot convert func literal (type func(map[string]int64, int, int) (dataframe.FilterAction, error)) to type dataframe.FilterDataFrameFn.

I'm very familiar with R DataFrame/Table and Pandas but dataframe-go's API is rather convoluted. The only web resource I found is this but the author also stated he couldn't understand the filter API.

Any help is appreciated, thanks!

You have to pass a function with the required signature, so vals must be a map[interface{}]interface{}. This is required because Go is not an interpreted language, and the code calling that function you passed as an argument has no compile-time knowledge of the function passed in.

Since your values are interface{}s, you have to convert them to the correct type to operate with them:
