i know this is a basic question, though i need some help because this
is somewhat away from my current issue, but nevertheless interesting
to me... Lets assume i have some estimated probabilities, say
estimated by a logit model. i know i can also state them as an odds

There is a good reason for the error in the
matrix case. Consider what would need to
happen for:
m[3, 5] - 100
to work.
Consistency might be a good thing here, but
if so I think it should be an error for the 1-D
case. This might be a useful difference between
1-D arrays and vectors.

distribution (it won't be, the data in this case LOOKS more poisson, or if I
explude the first week of results, a negative exponential; and in my other
case, cauchy is more

How to use sub, gsub, etc. to replace \ in a string to /?
For example,convert C:\foo\bar to C:/foo/bar.
If those are R strings, there are no backslashes in the first one. It
has a formfeed and a backspace in it.

Your example suggests you don't always want to keep the first

Hi R-Users,
I have a data frame containing year, month, day, and code columns. The
code column is a unique character of set ('E','A','B') - I am trying to
determine an efficient way of summarizing the count of each of these

Try this:
with(DF, tapply(code, list(year, month, code), length))
