elementName

name of list element in each sublist of x which contains a data frame

Value

data frame resulting from "row-binding" data frames.

x <- list(
  list(
    number = 1,
    data = data.frame(x = 1:2, y = 2:3)
  ),
  list(
    number = 2,
    data = data.frame(x = 11:12, y = 12:13)
  )
)
  
safeRowBindOfListElements(x, "data")
#>    x  y
#> 1  1  2
#> 2  2  3
#> 3 11 12
#> 4 12 13
  
# also working if the column names of the data frames in the "data" elements
# differ.
x[[1]]$data$z = 13:14
safeRowBindOfListElements(x, "data")
#>    x  y  z
#> 1  1  2 13
#> 2  2  3 14
#> 3 11 12 NA
#> 4 12 13 NA
