bindf: Bind Rows with Factors

Description

dplyr's bind_rows doesn't work well when the data frame has factors. This function handles factors before applying bind rows. Author: Bryce Chamberlain.

Usage

bindf(data.top, data.bottom, sort.levels = TRUE, ...)

Arguments

data.top

Data to be binded in the top rows.

data.bottom

Data to be binded in the bottom rows.

sort.levels

Sort the factor levels after combining them.

...

Other arguments passed to bind_rows.

Value

Binded data, with any factors modified to contain all levels in the binded data.

Examples

# NOT RUN {
# create data where factors have different levels.
df1 = data.frame(
  factor1 = c( 'a', 'b', 'c' ),
  factor2 = c( 'high', 'medium', 'low' ),
  factor.join = c( '0349038u093843', '304359867893753', '3409783509735' ),
  numeric = c( 1, 2, 3 ),
  logical = c( TRUE, TRUE, TRUE )
)#' 
df2 = data.frame(
  factor1 = c( 'd', 'e', 'f' ),
  factor2 = c( 'low', 'medium', 'high' ),
  factor.join = c( '32532532536', '304359867893753', '32534745876' ),
  numeric = c( 4, 5, 6 ),
  logical = c( FALSE, FALSE, FALSE )
)

# bindf preserves factors but combines levels.
# factor-friendly functions default to ordered levels.
str( df1 )
str( bindf( df1, df2 ) )
# }
