Hi all,
New to R, so this may be obvious to some.
I've been trying to figure this out for a while, I have a dataset "events"
that looks something like this:
Area NAME DATE X Xn Y
1 X 1/10/10 1 1 0
1 Y 1/11/10 0 0 1
1 X 1/12/10 1 0 0
1 X 1/12/10 1 0 0
1 X 1/12/10 1 0 0
2 X 2/12/10 1 1 0
2 X 2/12/10 1 0 0
2 Y 2/12/10 0 0 1
2 X 2/13/10 1 0 0
2 X 2/13/10 1 0 0
2 X 2/13/10 1 0 0
2 X 2/14/10 1 0 0
2 X 2/14/10 1 0 0
2 X 2/14/10 1 1 0
2 X 2/14/10 1 0 0
3 X 7/27/11 1 0 0
3 X 7/27/11 1 1 0
3 X 7/27/11 1 0 0
3 X 7/28/11 1 0 0
3 X 7/28/11 1 1 0
3 X 7/28/11 1 0 0
3 X 7/28/11 1 0 0
3 Y 7/28/11 0 0 1
3 X 7/28/11 1 0 0
3 X 7/28/11 1 1 0
3 Y 7/28/11 0 0 1
3 X 7/28/11 1 0 0
3 X 7/29/11 1 0 0
3 X 7/29/11 1 0 0
3 X 7/29/11 1 1 0
X and Y are events. Every row represents a single event happening, with a 1
indicating which one happens at that time. Xn indicates X happening at
night. I want to bootstrap these events over days but I think I need to
summarize them first, ie. get something that looks like this:
Area DATE X Xn Y
1 1/10/10 1 1 0
1 1/11/10 0 0 1
1 1/12/10 3 0 0
2 2/12/10 2 1 1
etc.
and then for each Area, bootstrap the data over the days. Any ideas? I've
tried using the 'reshape' package but I don't know how to sum over parts of
the columns as defined by the DATE values...
Many thanks ahead!
