* [SPARK-12232][SPARKR] New R API for read.table to avoid name conflictfelixcheung2016-01-191-1/+1

* [SPARK-12168][SPARKR] Add automated tests for conflicted function in Rfelixcheung2016-01-191-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently this is reported when loading the SparkR package in R (probably would add is.nan) ``` Loading required package: methods Attaching package: ‘SparkR’ The following objects are masked from ‘package:stats’: cov, filter, lag, na.omit, predict, sd, var The following objects are masked from ‘package:base’: colnames, colnames<-, intersect, rank, rbind, sample, subset, summary, table, transform ``` Adding this test adds an automated way to track changes to masked method. Also, the second part of this test check for those functions that would not be accessible without namespace/package prefix. Incidentally, this might point to how we would fix those inaccessible functions in base or stats. Looking for feedback for adding this test.

| | | | | | | | | | | | | | | | | * ```jsonFile``` should support multiple input files, such as: ```R jsonFile(sqlContext, c(“path1”, “path2”)) # character vector as arguments jsonFile(sqlContext, “path1,path2”) ``` * Meanwhile, ```jsonFile``` has been deprecated by Spark SQL and will be removed at Spark 2.0. So we mark ```jsonFile``` deprecated and use ```read.json``` at SparkR side. * Replace all ```jsonFile``` with ```read.json``` at test_sparkSQL.R, but still keep jsonFile test case. * If this PR is accepted, we should also make almost the same change for ```parquetFile```. cc felixcheung sun-rui shivaram Author: Yanbo Liang <ybliang8@gmail.com> Closes #10145 from yanboliang/spark-12146.

* [SPARK-12025][SPARKR] Rename some window rank function names for SparkRYanbo Liang2015-11-271-4/+4
| | | | | | | | | | | | | | Change ```cumeDist -> cume_dist, denseRank -> dense_rank, percentRank -> percent_rank, rowNumber -> row_number``` at SparkR side. There are two reasons that we should make this change: * We should follow the [naming convention rule of R](http://www.inside-r.org/node/230645) * Spark DataFrame has deprecated the old convention (such as ```cumeDist```) and will remove it in Spark 2.0. It's better to fix this issue before 1.6 release, otherwise we will make breaking API change. cc shivaram sun-rui Author: Yanbo Liang <ybliang8@gmail.com> Closes #10016 from yanboliang/SPARK-12025.

| | | | | | | | | | | | Add subset and transform Also reorganize `[` & `[[` to subset instead of select Note: for transform, transform is very similar to mutate. Spark doesn't seem to replace existing column with the name in mutate (ie. `mutate(df, age = df$age + 2)` - returned DataFrame has 2 columns with the same name 'age'), so therefore not doing that for now in transform. Though it is clearly stated it should replace column with matching name (should I open a JIRA for mutate/transform?)

| | | | | | | | | | | | | | | - Add `when` and `otherwise` as `Column` methods - Add `When` as an expression function - Add `%otherwise%` infix as an alias of `otherwise` Since R doesn't support a feature like method chaining, `otherwise(when(condition, value), value)` style is a little annoying for me.
