Hi,
Can someone help for a R question?
I have a data set like:
Name CheckInDate Temp
John 1/3/2014 97
Mary 1/3/2014 98.1
Sam 1/4/2014 97.5
John 1/4/2014 99
I'd like to return a dataset that for each Name, get the row that is the latest
CheckInDate for that person. For the example above it would be
Name CheckInDate Temp
John 1/4/2014 99
Mary 1/3/2014 98.1
Sam 1/4/2014 97.5
Thank you for your help!
Richard
