[R] Keep date, strip time?

[Mark Knecht]

I have hundreds of CSV files coming in from another program that have
a text field representing the date & time combined together. I need to
strip the time and keep the date. How could I do that?

In the example below, on the first line I need to keep the 6/15/2009,
turning it into a date that R recognizes, but I need to throw away the
time portion completely.


> read.csv("C:\\D1\\F1-V1.csv", header=FALSE)[,c(1,7)]
                       V1    V7
1   6/10/2009 10:04:00 AM    91
2    6/15/2009 9:47:00 AM  -279
3    6/15/2009 9:47:00 AM   861
4    6/22/2009 9:47:00 AM   771
5    6/22/2009 4:01:00 PM  -179
6    6/24/2009 2:53:00 PM    61
7     7/2/2009 9:47:00 AM   491
8     7/6/2009 9:47:00 AM    81
9   7/13/2009 10:04:00 AM  1681

Thanks,
Mark
