Systematically biased count data regression model
Dear all, I am attempting to explain patterns of arthropod family richness (count data) using a regression model.

how to convert a data.frame to a list of dist objects for individual differences MDS?
I have a 45 x 16 data frame consisting of dissimilarities among 10 colors, giving in each column the 45 = 10*9/2 pairwise judgments for one of 16 subjects. The rownames identify each pair of colors, e.g, "AC" = ("A","C"), and the pairs are ordered by columns in the lower triangle of each distance matrix. > helm.raw <-

iterating over groups of columns
I am mainly a Java/C++ programmer, so my mind is used to iterating over data with for loops. After a long break, I am trying to get back into the "R mindset", but I could not find a solution in the documentation for the applys, aggregate, or by. I have a data.frame where each row is an entry with 10 groups of measurements. The first measurement spans 1 column, the second spans 2
