I have no problems with displaying the fields (after I pumped the data into MySQL manually outside of RoR), but when I try to edit a record, it =does= save the changes in the primary record, but =not= the join table.

ListeRs, Within the last two months, I thought I saw mention of an R function that would create a new data frame composed of duplicates or multiple copies of rows of an input data frame given one or several columns of values indicating how many times each row should be copied. As a simple example, given a dataframe: > in.df x y 1 A 1 2 B 2 3 C 3 "func.name (in.df, in.df$y)"

Hi all. I''m interested in contributing to Rails as a next step in software development. I''m sure there''s tons of things to learn while working on a widely used, rather complex project.

R-users, I'm seeking any suggestions on optimizing some code for speed. Here's the setup: the code below is part of a larger chunk that is calculating Fst values across loci and alleles. This chunk is designed to calculate the proportion ('p.a') of an allele ('a') at a locus in each population ('p') and the proportion of individuals heterozygous for that

List gurus, I'm trying to code a Gompertz growth curve function as part of a larger project and have run across a problem due to my ignorance of environments. Some sample data and the function are as follows: growth <- data.frame(age = c(1.92, 3, 5.83, 3.17, 15.5, 1.17, 5.58, 13.33, 14.29, 5.83, 13.79, 6.33, 13.75, 16.83, 13, 11.67, 0.25, 1.73, 9.46, 5.67), length = c(157, 165, 179,

R-help, I'm getting some unexpected behavior with subsetting a data frame (aircraft flight data) that I can't sort out.
