Type & Coercion Errors

Names do not match (rbind)

Matches: names do not match previous names

WHAT THIS ERROR MEANS

You tried to rbind() or bind_rows() data frames that have different column names. All data frames must have matching column names.

1. Check column names with names() on each data frame.

2. Rename columns to match before binding.

3. Use dplyr::bind_rows() which is more forgiving than rbind().

BAD — THIS CAUSES THE ERROR

rbind(data.frame(x = 1), data.frame(y = 2))

GOOD — CORRECT APPROACH

library(dplyr)
bind_rows(data.frame(x = 1), data.frame(x = 2))
