• Index is a generic function for extracting the index of objects, currently it has a default method and a method for zoo objects which is the same as the time method for zoo objects. Another pair of generic functions provides replacing the index or time attribute. Methods are available for 'zoo' objects only, see examples below. The start and end of the index/time can be queried.

Zoo is particularly aimed at irregular time series of numeric vectors/matrices, but it also supports regular time series (i.e., series with a certain frequency). Zoo's key design goals are independence of a particular index/date/time class and consistency with ts and base R by providing methods to standard. Manipulating Time Series Data in R with xts and zoo.

Ok, first off, let me welcome you to the AR Cheat Page. If you are not looking for a way to cheat on the Accelerated Reader program, then LEAVE. If you are, then you've come to the right place! Below are instructions on how to get just about how many ever points you need. Now, if you don't care about how/why I came up with this system, skip to below the divider. If not, read on

Well, let's start with WHY I'm doing this. I'm a computer programmer (yes, at 13 years old) and my school adopted the AR program when I was in 5th grade (I'm in 8th now), so since I had to get x amount of points to maintain a good average. Now, I didn't mind too much about the reading part, BUT, instead of reading my computer books, I had to read all of these fiction books that didn't help me at all! I could have stacked my computer books (that I wanted to read) up to two feet thick! So, you see my problem? I'm an efficient person, I don't waste my time, and I wasn't about to let this stand in my way!

So, you might also ask HOW I came up with the system? Well, in my reading classroom (where you take tests), there are 3 computers next to eachother. All three are used for taking tests. Some of my friends and I sometimes sat next to each other and took the same tests. We noticed the the choices were randomized (what choice would be A one time, could be C the next), but we were about to look at the text and still cheat. This method, however, was not robust. The teacher could see that we were taking a test on the same book and were on the same question. Something had to be done. I used my brain and came up with this ROBUST system!

Although I am in eighth grade now and am done taking reading class, I do feel the pain of my fellow humans, so I made this.

Ok, first let me teach you the format the answers are written in. If the 'answer' is '1', then you choose the SHORTEST answer. If the 'answer' is '4', then you choose the LONGEST answer. If the 'answer' is '2', you choose the next to shortest answer. Finally, if the 'answer' is '3', then you choose the next to longest answer'. You may be confused. Let me give you an example:
