strange problem with strptime and date variable
Hello all,
I am manipulating a large database with 70,000 records. "strptime" generates
a date variable but R treats some of the values as NA. I attach a simple
example below.
I have spent hours on this problem. Any hint would be greatly appreciated.
Many thanks,
Edwin Sun
