R help - Feb 2009 - (no subject)

Is there a general method for finding out what "something" is in R
please.

 

I have a list (bycontract) that;

 
> is.list(bycontract3)
[1] TRUE

 

And an element of this list would be this say;

 
> bycontract3[[1]]
 [1]  22   3.2  -8 -17  49   3

 [7]  30 -3 -21   8 3 12

[13]  49 19 -13  -2 25 39

[19] -12 -90 -1  15 -87 30

 

I can not seem to see what type of object this element is (is.list = FALSE)
- also is there a way to take all the elements and just put them in just one
series please

 

Regards

Dear Glenn,

Are you looking for str()? Try str(bycontract)

To call in the statistician after the experiment is done may be no more
than asking him to perform a post-mortem examination: he may be able to
say what the experiment died of.

The combination of some data and an aching desire for an answer does not
ensure that a reasonable answer can be extracted from a given body of

You first need to look at the documentation for the mode, class and  
typeof functions. (This should have been covered early in any of the  
standard texts.)

You are using the function "[[" on a list with one element and it  
appears you are getting a vector.

Try:

is.vector(bycontract[[1]])

mode(bycontract)
class(bycontract)
typeof(bycontract)

this.thing <- bycontract[[1]]
mode(this.thing)
class(this.thing)
typeof(this.thing)

Now you have in "this.thing" what some people outside R might call  
"just one series", but R users would call a "vector". There
are very
useful indexed series objects of class "zoo", but it doesn't
appear as
though you are quite ready for that level of complexity. Install and  
load the zoo package for addition of that facility when you are ready .
