Seems to work fine in my testing:

PLEASE do read the posting guide http://www.R-project.org/posting-guide.html
and provide commented, minimal, self-contained, reproducible code.

Similarly, the following command produces the same error:
? ?as.Date("NA")

However, as.Date(NA) performs as documented.

Can we enhance the as.Date() function to convert "NA" strings into NA
value prior to type conversion?

I sincerely appreciate the help, but with all due respect, I have read
the posting guide and did provide the minimal code necessary to
reproduce the desired feature. To reiterate, I would like to be able
to feed the character string "NA" to the as.Date() function to yield
the same result as `as.Date(NA)`. Please advise if testing the
following does not yield an error:

as.Date("NA");

This may or may not aid the read.csv() error message in my particular
code (for which a workaround has already been identified).

Thank you.
