Participants,
I have had difficulty in using the DateList function.
I am to convert string dates "mm/dd/yyyy" to a date list
{YYYY,MM,DD,0,0,0}.
I have large data sets of approx. 400,000.
Using the following routine, Mathematica hangs and does not produce any
result.
Corrected Routine;
lst=Range[1,Length[data]];
ParallelMap[DateList[{data[[#,5]],{"Month","/","Day","/","Year"}}]&,lst]
Abort does not work. I need to do a hard Mathematica close.
The problem seems to occur when the dataset is between 200,000 and 300,000.
The routine has worked with data sets of less than 200,000.
Any idea as to what causes the problem?
Microsoft 7 (64bit), 18Gigs memory, Intel Xeon
Mathematica 8.04
Thank You,
Ben
