Hello, I am a new R user and have a question regarding dendrogram coloring. I would like to color each leaf in the dendrogram (dhc) according to a specific criterion. For me this criterion is the gene name. For this, I created a data.frame with 2 variables: The gene name and the corresponding col

[R] comparing real set vs sampled sets

Dear R helper, I have a statistic question. I have a vector of 500 values for which I need to assess the statistical significance of occurrence real.dist <- realValues For that, I sampled from my data large data pool 1000 other vectors of 500 values each. I then run ks.test with my real vec vs

[R] subselecting on Data frame

Dear all, I have a data frame of features (example pasted below) from which I would like to select, say: how many triplets of features (corresponding to rows) have the same Scaff and the same "Cat" and a score >0.6 and fall in a distance of max 1 (distance defined as Start of row[i+1] - End o

[R] obtain triplets from Data Frame columns

Hi Guys, I have a list elements in two columns of a data frame. I want first to subselect on V1 and then to form and count all possible and unique triplets of V1 with the corresponding elements in V2 but exclude triplets for which a pair (V1 V2) does not exists: Example input V1 V2 AB A

Re: [R] dependent column(s) in data frame

Many thanks David, I will have a look on logistic regression for my case. Do you know about a good example regarding logistic regression ? I was thinking also of using Multiple Factor Analysis too (MFA - like in FactoMineR). However I am not sure how successful this is going to be. Best, P. -

Re: [R] dependent column(s) in data frame

Well I first thought of using the MFA by considering my data as categorical but indeed the correspondence analysis methods are better suitable for my data structure, Thanks again, P -- View this message in context: http://r.789695.n4.nabble.com/dependent-column-s-in-data-frame-tp4685561p46857

[R] Apply function over elemetns of a list

Hello, I have a list "ll - see below" on which I would like to apply a function accessing every pair of elements in the list. For instance, I want to apply the "sum" function on "6635 + 6636" and return the sum, the on "6635 + 6637", ... Any hint to do that using apply / mapply / rapply ? Than
