merge_columns: rbind two or more data frames with different columns

In revtools: Tools to Support Evidence Synthesis

Description

Take two data.frames with arbitraily different numbers and names of columns, and rbind them together.

Usage

merge_columns(x, y)

Arguments

x	A data.frame, or a list containing multiple data.frames.
y	An optional second data.frame. Only used if x is not a list.

Value

An object of class 'data.frame', containing data from all input data frames. That is, all unique columns are preserved, while rows that are missing data for a given column are assigned NA.

Examples

# import some data
file_location <- system.file(
  "extdata",
  "avian_ecology_bibliography.ris",
  package = "revtools")
x <- read_bibliography(file_location)
y <- x[, 1:3]
z <- merge_columns(x, y)
# or equivalently
z <- merge_columns(list(x, y))
