combinedata: Combine datasets using dplyr's bind and join functions

Description

Combine datasets using dplyr's bind and join functions

Usage

combinedata(dataset, cmb_dataset, by = "", add = "", type = "inner_join",
  name = "", data_filter = "")

Arguments

dataset

Dataset name (string). This can be a dataframe in the global environment or an element in an r_data list from Radiant

cmb_dataset

Dataset name (string) to combine with `dataset`. This can be a dataframe in the global environment or an element in an r_data list from Radiant

by

Variables used to combine `dataset` and `cmb_dataset`

add

Variables to add from `cmb_dataset`

type

The main bind and join types from the dplyr package are provided. inner_join returns all rows from x with matching values in y, and all columns from x and y. If there are multiple matches between x and y, all match combinations are returned. left_join returns all rows from x, and all columns from x and y. If there are multiple matches between x and y, all match combinations are returned. right_join is equivalent to a left join for datasets y and x. full_join combines two datasets, keeping rows and columns that appear in either. semi_join returns all rows from x with matching values in y, keeping just columns from x. A semi join differs from an inner join because an inner join will return one row of x for each matching row of y, whereas a semi join will never duplicate rows of x. anti_join returns all rows from x without matching values in y, keeping only columns from x. bind_rows and bind_cols are also included, as are intersect, union, and setdiff. See http://radiant-rstats.github.io/docs/data/combine.html for further details

name

Name for the combined dataset

data_filter

Expression used to filter the dataset. This should be a string (e.g., "price > 10000")

Value

If list `r_data` exists the combined dataset is added as `name`. Else the combined dataset will be returned as `name`
