\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	AFTSurvivalRegression in SparkR ## What changes were proposed in this pull request? This PR continues the work in #11447, we implemented the wrapper of ```AFTSurvivalRegression``` named ```survreg``` in SparkR. ## How was this patch tested? Test against output from R package survival's survreg. cc mengxr felixcheung Close #11447 Author: Yanbo Liang <ybliang8@gmail.com> Closes #11932 from yanboliang/spark-13010-new.
*	[SPARK-13449] Naive Bayes wrapper in SparkR	Xusen Yin	2016-03-22	1	-0/+59
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	## What changes were proposed in this pull request? This PR continues the work in #11486 from yinxusen with some code refactoring. In R package e1071, `naiveBayes` supports both categorical (Bernoulli) and continuous features (Gaussian), while in MLlib we support Bernoulli and multinomial. This PR implements the common subset: Bernoulli. I moved the implementation out from SparkRWrappers to NaiveBayesWrapper to make it easier to read. Argument names, default values, and summary now match e1071's naiveBayes. I removed the preprocess part that omit NA values because we don't know which columns to process. ## How was this patch tested? Test against output from R package e1071's naiveBayes. cc: yanboliang yinxusen Closes #11486 Author: Xusen Yin <yinxusen@gmail.com> Author: Xiangrui Meng <meng@databricks.com> Closes #11890 from mengxr/SPARK-13449.

*	[SPARK-12034][SPARKR] Eliminate warnings in SparkR test cases.	Sun Rui	2015-12-07	1	-0/+115
	This PR: 1. Suppress all known warnings. 2. Cleanup test cases and fix some errors in test cases. 3. Fix errors in HiveContext related test cases. These test cases are actually not run previously due to a bug of creating TestHiveContext. 4. Support 'testthat' package version 0.11.0 which prefers that test cases be under 'tests/testthat' 5. Make sure the default Hadoop file system is local when running test cases. 6. Turn on warnings into errors. Author: Sun Rui <rui.sun@intel.com> Closes #10030 from sun-rui/SPARK-12034.
