2015-03-29 ~ 2015-09-22 Wush Wu - Version 0.9.1 - Include two vignettes. - Change the default behavior of `hashed.model.matrix`: - The `signed.hash` is disabled. - The output of `split` with type `\"existence\"` will filter the collision. - Add a helper function to calculate the index of interaction. - Add progress bar to `hashed.model.matrix`. - Add the type `tf-idf` to split. 2015-01-01 ~ 2015-03-28 Wush Wu - Version 0.9 - Enhance the documentations. - Rename the original API: - tag ==> split - hash_size ==> hash.size - is.create_mapping ==> create.mapping - Change the default argument: - transpose ==> FALSE - is.dgCMatrix ==> TRUE - The empty string after `split` is skipped. - The attribute `mapping` returned by `hashed.model.matrix` is the indices in the matrix now. - Add two API and add Michael Benesty to the Author list: - hash.mapping : extract the `mapping` table from the returned matrix by `hashed.model.matrix`. - hash.size : suggest a hash size. - Add an API for documentation intToRaw and remove the package pack from Suggests . 2015-01-01 Wush Wu - Version 0.8.1 - Change the API - Default `transpose` to `FALSE` - Add the argument `is.dgCMatrix` and the default value is `TRUE` - Version 0.8 - Use the implementation of murmurhash3 from the package digest - Update the author list - Fix the following bugs - Undefined behavior due to big endian system - Inconsistent interaction result due to big endian system - Incorrect indices when expanding tag feature. See #27 - Correct some document errors in DESCRIPTION and Manual
