You can specify the same type parameter in either lines() or points()
that can be used in plot(). So, if you want to show points as well as
lines, use the following:

y - c(3,5,2,4,1,4)

It's definitely not random! Try apply(at,3,I) to see what the
marginal table is that max operates on, and you'll see where your
result comes from.

It just seemed wierd because over a 2d array, it also returns vectors,
but I guess breaking things down into components of the list it makes
sense. Besides, using David's suggestion of apply(at, MARGIN, I) also
offers the insights I need.

A quick question!
The number of episodes per year of otitis media follows a Possion
distribution with lambda = 1.6 episodes per year. Wouldn't the
probability of getting 3 or more episodes of otitis media in the first
2 years of life be:
ppois(q=3, lambda=1.6*2, lower.tail = TRUE, log.p =
Is that 6 deaths over 20 years? If so, the probability of getting
exactly 6 deaths is given by
dpois(6,1.8)
[1] 0.007808587
The probability of getting six or more deaths is 1 minus the result
you obtained.

A similar question was asked last month.

In a normalized database, you should store the index and value in separate
columns.
I recommend mine, which is listed in CRAN,

Not withstanding Prof. Heiberger's admirable enthusiasm, I think the
canonical answer is probably MASS (Modern Applied Statistics with S) by
Venables and Ripley. It is very comprehensive, but depending on your
background, you may find it too telegraphic.
