I think I am using the improved version of setdiff(...) that handles data.frames, so I think some odd behavior was expected but this one is escaping me. It appears that the the addition of duplicate entries is not caught by the setdiff(...). Is this expected behavior? If so, is there another method or approach that should be used to identify duplicate row entries between two different data

I am trying to install the maverick version. The lucid version works flawlessly, but this one promts this messages. The following packages have unmet dependencies: r-base: Depends: r-base-core (>= 2.12.0-1maverick0) but it is not going to be installed Depends: r-recommended (= 2.12.0-1maverick0) but it is not going to be installed Recommends: r-base-html but it is not going

Thanks to Jay Kerns and Jim Lemon for their help. It's exactly what I wanted and "aggregate" is very efficient even with a huge data. Thanks "G. Jay Kerns" <gkerns@ysu.edu> a écrit : Hi Louis, If I am understanding your question correctly, here is one way: suppose your matrix is M of dimension n x k. D <- data.frame(M) # convert to data frame ones <- rep(1, n) # a column of 1s Now you can count the number of repeats of each unique row. aggreg...

HI, i'm really new of R and i need some help. I have to describe some distributions for some dices throw: - launching 3 dices i need the distribution of the sum of the two higher values - launching 4 dices i need the distribution of the occurrences of the same value possibly i need a way to compare the two distribution adding the fourth dice to the first without summing it (only for

Hi, I fail to find "choose.dir()" in my current R install (see below)? Didn't that exist at some point? How to achieve "file.choose()" equivalent functionality for directories?

Dear R users, ?rgamma gives me : rgamma(n, shape, rate = 1, scale = 1/rate) rate: an alternative way to specify the scale. The Gamma distribution with parameters ‘shape’ = a and ‘scale’ = s has density f(x)= 1/(s^a Gamma(a)) x^(a-1) e^-(x/s) Should I understand that scale=1/rate ? Is it written somewhere ? Then

Hi, I have a bright, diligent second-year graduate student who wants to learn statistics and R and will, in effect, be taking a tutorial from me on these subjects. (If you've seen some of my questions on this list, please don't laugh.) As an undergrad he majored in philosophy, so this will be his first foray into computer programming and statistics. I'm thinking of having him use

  Dear R helpers   Suppose I have two sets of ranges (interest rates) as   Range 1 : (7 – 7.50, 7.50 – 8.50, 8.50 – 10.00) with respective probabilities 0.42, 0.22 and 0.36.     Range II : (11-12, 12-14, 14-21) with respective probabilities 0.14, 0.56 and 0.30 respectively.     My problem is to form the combinations of these ranges in a decreasing order of joint probabilities. It is assumed that
