Once you install dplyr, you can use function in a qualified manner exactly as @cole demonstrated: dplyr::bind_rows and/or dplyr::bind_cols. In that case you don't need to add library(dplyr) to your script.
If you do add it, then you can use it without a qualifier (bind_rows/bind_cols), but I would say that first variant is better as it makes it abundantly clear where functions are coming from.
