I've never used an R command without reading the documentation first. I think
that would be impractical. I am not an expert at deciphering the documentation
though and I post here because I did in fact read the documentation, do
extensive google searches, ask friends/collegues and still find no
Re-sizing within the dev command works well. I'm not sure why I would need the
dev.off(). I have the plot commands run. Then I have the dev.copy2pdf command.
Thanks again for your help.

I just saw this post:
http://r.789695.n4.nabble.com/X11-plot-window-sizes-td900509.html
where is explains that the window size cannot be larger than 85% of your
screen. I'm not sure what you are referring to about the copying the whole
region, not just the plot. Also, I remember using the width a
This code works great. I will improve my descriptions of what I want in the
future. Thanks for the help.

Thanks all for the replies. I am getting better slowly but surely. I imagine
that I will get better at figuring out things as well so I don't have to post
as many questions. I do lots of searches, but still cannot figure out how to do
everything that I need.
The new code is as such:
par(mfrow=c
Easy fix. Under ?par, I don't see where I can enter an overall title. Should I
add a text command or something?

The problem with using cumsum, is that the measured output is the cumulative
feed consumed throughout the day. When the animals do not eat for 30 minutes or
so, it will not output a new value, but as soon as they do eat, the scale will
weigh the difference and then output the cumulative feed eat
I am still working on the weights problem. If the animals do not eat (like
after sunset), then no new feed weight will be calculated and no new row will
be entered. Thus, if I just use the previous value, it should be correct for
how much cumulative feed was eaten that day up to that point.
I wi
Good deal. I will do that in the future. Thanks.

Thanks, that did exactly what I wanted. I realize that I didn't put it in the
best form, but was having trouble coming up with a replicable example. I see
that many people here quickly create examples and I am learning how to do that,
but still struggle, especially when using as.POSIXct and othe
I am already using that to combine the date and time (I had it in the code, but
took it out for the post to simplify it), but I still have the problem where I
want to remove any time before 6am across all dates.

An easy way to average every 30 minutes is using the aggregate function. First
I use the mod (%%) to get times as the next earliest possible 30 min time
increment.
bTime<- as.POSIXct(c( "2011-04-28 09:02:00 CDT","2011-04-28 09:02:00
CDT","2011-04-28 09:12:00 CDT","2011-04-28 09:14:00 CDT","20
I figured out a poor way to do what I want.
meas<-runif(30)
times<-sort(runif(30))
timesdec<-seq(0,1,0.2)
ltim<-length(timesdec)
storing<-rep(0,ltim)
for (i in 1:ltim) {
if (i=1) {rowstart=1} else {rowstart<-findInterval(timesdec[i-1],times)+1}
rowfinal<-findInterval(timesdec[i],times)
storing[i]
Beautiful.

Here is an example of what I would like to do:
meas = measurements
times = time of measurement
measf = measurements in final, reduced matrix

Taking the final value for each 30-minute interval seems like it would get what
I want. The problem is that sometimes this value would be 15 minutes before the
end of the 30-minute interval. What would I use to pick up this value?
