Examples

# Example factor vector
factor_vec <- factor(c('A', 'B', 'C', 'D'))

# Pad levels to width 4 using '0' as padding character
padded_factor <- ft_pad_levels(factor_vec, width = 4, pad_char = '0')
print(levels(padded_factor))
# Output: "000A" "000B" "000C" "000D"

# Pad levels to width 6 using '%A' as padding string
padded_factor <- ft_pad_levels(factor_vec, width = 6, pad_char = '%A')
print(levels(padded_factor))
# Output: "%%A%A" "%%A%B" "%%A%C" "%%A%D"
