Description

Graft one dataset onto another

Usage

graft(.data, combine_fun, data2)

Arguments

.data

A tbl or something that can be coerced into one

combine_fun

optional, A function that will combine two tbls such as full_join or bind_rows

data2

A tbl or something that can be coerced into one

Value

A single tbl object

Details

Graft requires two data objects. The first must be provided by the user. The second can either be passed in or automatically pulled off of the package's internal stack of scions. These will be combined accoring to the following rules in order:

• If either dataset has zero rows, the other dataset will be returned.

• If combine_fun is specifed, combine_fun(.data, data2) will be called

• If all column names match, a row bind will occur

• If at least some column names match, a full join will occur

• If both have the same number of rows a column bind will be performed

Examples

# NOT RUN {
library(dplyr)
aframe <- data.frame(zed = runif(100))
set_to_zero <- . %>% mutate(zed = 0)
aframe %>% scion(zed >0.5, false_fun=set_to_zero) %>% mutate(zed=1) %>% graft

# }
