csv-seq-filename->format-seq clj

(csv-seq-filename->format-seq k-means-state key)

Converts a csv file into another file type and returns a k means object with an updated key name.

CSV isn't a well optimized format for doing large computations.
Computing the min and max of each column working with optimized csv seqs can take two orders of magnitude longer than the same operations performed against arrow streams.

dataset-seq->column-names clj

(dataset-seq->column-names ds-seq)

ds-seq->rows->maps clj

(ds-seq->rows->maps ds-seq rows)

extension clj

(extension filename)

Returns a filenames last file extension.

file? clj

(file? filename)

Returns true if a file exists and false otherwise.

filename->format clj

(filename->format filename)
