[R] Plotting cumsum data using lattice plots according to date conditioned by name.

[Shawn Way]

I've been playing around with data like the following:

Name    Date    Hrs
Way, S  2-3-12  8
Nun, B  2-3-12  9
Way, S  2-4-12  7.5
Nun, B  2-4-12  9
Gus, T  2-5-12  8

I've been able to take this into a data.frame and even develop a cumsum 
for each of the people

d.cum <- with(data,by(Hrs, 
INDICES=list(date=as.POSIXct(Name)),FUN=cumsum))

This gives me a list personnel with an array of cumulative hours, without 
any dates associated with the cumulative hours.

What I've been trying to do is develop a conditioned lattice xyplot that 
allows the cumulative hours be plotted according vs date conditioned with 
the person's name.

I've tried using something like this to try to create a data.frame for 
plotting, with only mild sucess.

data.frame(date=as.POSIXct(Date[Name[2]]),hours=d.cum$`Way, 
S`,name=rep("Way, S",length(d.cum$`Way, S`)))

and 

d.data <- as.data.frame(do.call("rbind",d.cum))

all to no avail.

Can anyone point me in a good direction as to whatto look at next?


Thank you kindly,
