Comparing Character Vectors Per Row in R if Same True/False

I'm missing something very simple here.

I tried referring to This Post

I'm trying to compare 2 character vectors to see if they equal each other on a per row basis, just expecting a TRUE / FALSE result per row. (Trying to find the FALSE)

all(data.frame(dBase$process_name == dBase$import_process))

When I run the above I receive the result: 

Error in FUN(X[[i]], ...) : only defined on a data frame with all numeric variables

I tried this as well but it seems to be overall, not per row.

identical(dBase$process_name, dBase$import_process)

So is there an alternative to comparing characters / strings to see if they are the same and pull up the rows were FALSE occurs?

If dBase is the name of an existing data.frame, then you can do the following to see all the rows where process_name and import_process are not identical. Notice that I use the != to get only those where they are not equal.

dBase[ dBase$process_name != dBase$import_process, ]
