OpenML 1.8 (Release date: 2018-03-02): =========== - Fixed bug in listOMLSetup. - Update to curl 3.1 which fixes the error 'transfer closed with outstanding read data remaining' for large files. - New function extractOMLStudyIds added, which directly extracts ids of data sets, tasks, flows and runs. OpenML 1.7 (Release date: 2017-10-17): =========== - listOMLTask, listOMLFlow, listOMLRuns do not return the tag field anymore. - New function listOMLSetup added, which enables extracting hyperparameter configurations of specific setups/flows. - New function chunkOMLlist added in order to automatically do chunked listing requests. OpenML 1.6 (Release date: 2017-08-14): =========== - Fixes some config issues. OpenML 1.5 (Release date: 2017-08-11): =========== - New functions to list and get all information w.r.t. studies: getOMLStudy, listOMLStudies. - API key not needed anymore for getOML* and listOML* functions. OpenML 1.4 (Release date: 2017-06-20): =========== - Bugfix: Error message "Start tag expected, '<' not found" for getOMLTask and getOMLDataSet was fixed. - as.data.frame methods for OMLRunParList, OMLDataSet and OMLTasks objects were added. - listOMLRunEvaluations now allows to get results w.r.t. a single evaluation measure ('evaluation.measure' arg) which speeds up the request. - listOMLRuns and listOMLRunEvaluations now also supports a vector of ids for task.id, flow.id and uploader.id. - getOMLRun(run.id, only.xml = TRUE) can now be used to get the run without the predictions arff file (which is faster, especially when you are only interested in, e.g. getting the hyperparameters of a run). OpenML 1.3 (Release date: 2017-04-01): =========== - Bugfixes. - Updated citation. - Add html vignette and update its content. - listOMLTasks and listOMLDataSets now additionally show a message when the limit of results is reached. - listOML* functions return an empty data frame when no results are available. - listOMLRunEvaluations now returns additional columns for the flow (flow version, flow source and learner name). - runTask now allows to set the 'models' option to FALSE so that resulting objects will be smaller. OpenML 1.2 (Release date: 2017-02-07): =========== - Add support for multilabel datasets and tasks. - Replace download.file with httr::GET. - Add mlr 2.10 dependency (we internally use mlr::mergeBenchmarkResults and mlr::makePrediction now).
