[SPARK-14883][DOCS] Fix wrong R examples and make them up-to-date
## What changes were proposed in this pull request?
This issue aims to fix some errors in R examples and make them up-to-date
in docs and example modules.
- Fix the wrong usage of map. We need to use `lapply` if needed. However,
the usage of `lapply` also needs to be reviewed since it's private.
```
-teenNames <- map(teenagers, function(p) { paste("Name:", p$name)})
+teenNames <- SparkR:::lapply(teenagers, function(p) { paste("Name:",
p$name) })
```
- Fix the wrong example in Section `Generic Load/Save Functions` of
`docs/sql-programming-guide.md` for consistency
- Fix datatypes in `sparkr.md`.
- Update a data result in `sparkr.md`.
- Replace deprecated functions to remove warnings: jsonFile -> read.json,
parquetFile -> read.parquet
- Use up-to-date R-like functions: loadDF -> read.df, saveDF -> write.df,
saveAsParquetFile -> write.parquet
- Replace `SparkR DataFrame` with `SparkDataFrame` in `dataframe.R` and
`data-manipulation.R`.
- Other minor syntax fixes and a typo.
