Column-bind data frames or vectors of unequal lengths

Source: R/FUNCTIONS.R
c_bind.Rd

Combines any number of data frames or vectors side by side, padding shorter inputs with NA rows so all columns reach the same length. Each input's columns are prefixed with the object's name to avoid duplicate column names. Vectors are coerced to single-column data frames before binding.

Usage

c_bind(..., first = TRUE)

Arguments

...

Data frames or vectors to column-bind. Names are taken from the unevaluated expressions passed (e.g. variable names).

first

Logical. When TRUE (default) NA padding rows are appended at the bottom of shorter inputs; when FALSE they are prepended at the top.

Value

A data frame with one column per column across all inputs, padded with NA rows to the length of the longest input. Column names follow the pattern <object_name> for single-column inputs and <object_name>_<original_colname> for multi-column inputs.
