When I import a Stata (version 7) data set into R, the missing values
for factor and numeric variables are represented as "NaN", but the
missing values for date variables are represented as "NA". Can "NaN"
for numeric variables be treated as the same as "NA" ? Are there
situations when these two representations are not equivalent?
The following are the details of my system:
system x86, Win32
