Not sure that solution properly focuses the unique function on the
first column, and even when I tried to do so, my code using did not
produce what I expected. The unique function does not return a logical
vector.
Try:
ships[!duplicated(ships$type), ]
And Rajasekaramya, please include code that creates the test data next
time.

Let's not spend our time and resources thinking about things that are
so little or so large that all they really do for us is puff us up and
make us feel like gods. We are mammals, and have not exhausted the
annoying little problems of being mammals.
