Hello -
I have a csv file with a few date columns. Some of the records have an
"NA" character string instead of the date. When I attempt to use
read.csv() and typecast the columns using colClasses, I receive the
following error:
Error in charToDate(x) :
character string is not in a standard unambiguous format
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?
Thanks!
