Re: [R] Finding overlaps in vector

But cutree does away with the indexes from the original input, which rect.hclust retains. I will have no other choice and match that input with the 'values' contained in the clusters ... Joh Gabor Grothendieck wrote: If we don't need any plotting we don't really need rect.hclust at all.

If you want indexes, i.e. 1, 2, 3, ... instead of the values in v you can still use split -- just split on seq_along(v) instead of v (or if v had names you might want to split along names(v)): split(seq_along(v), ct) and if you only want to retain groups with 2+ elements then you can just Filter

[R] Understanding eval

After many hours of debugging code, I came to the conclusion that I have a fundamental misunderstanding regarding eval, and hope that someone here can explain to me, why the following code acts as it does: foo - function(expr) { eval(substitute(expr), envir=list(a=5),

[R] vector distribution

Hi everyone, say i have a population (stable) with different amounts of animals in every ageclass (80 of age 1, 60 of age 2, etc) in a vector. Can anybody tell me how i can add gender (male or female) to all ageclasses? I want a 1:1 ratio of males and females within the population (as a

[R] number of count of each unique row

Hi, I have a matrix of duplicate rows. How to output a list the unique rows with their count? I have used unique to have the unique rows, but can't produce the occurences of each unique row. Thanks Louis - [[alternative HTML version

Re: [R] number of count of each unique row

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. aggregate( ones, by = as.list(D),

Re: [R] Understanding eval

Duncan has already pointed out that consideration of promises is what is missing in the description but in addition the way lm and other functions in R get around it is to use match.call like this: bar2 - function(er) { mc - match.call() mc[[1]] - as.name(foo)

Re: [R] Understanding eval

That's a very good idea. I'll have to see if and how it applies to the more general case I'm dealing with. ( Essentially I am trying to create tkcbind and tkrbind kind of functions, that group together tcltk widgets under a new frame they create, and the frame has to be created before the
