R help - Dec 2007 - Function to tell you how an object is put together

Question: Suppose I have an arbitrary object. Is there a function which will 
accept the object as an argument and sort of give the format of  the object, 
how it is put together, etc.? The analysis would include the attributes and 
the names of the attributes. Also, things like whether or not the object is 
an array; whether or not it is a matrix, etc.

str goes a long way in doing that

probably you're looking for str(), e.g.,

lis <- list(x = 1:10, y = letters[1:3])
str(lis)


I hope it helps.
