[R] How to identify data structure?

[Sarah Goslee]

str() is the most informative; class() may also be helpful.

> data(AirPassengers)
> class(AirPassengers)
[1] "ts"
> str(AirPassengers)
 Time-Series [1:144] from 1949 to 1961: 112 118 132 129 121 135 148
148 136 119 ...

For cases like this, with data included in R and documented,
?AirPassengers
is also useful. You might also want to read ?ts
