Hi everyone, I''m working on my first Rails project and I''d like some input before I get started coding in earnest. My previous Web app development experience has been in standard Python CGI and Zope. I''m here to find out more about Rails.

You can make this much more readable with apply functions. result <- apply( all_combine1, 1, function(x){ p.value <- sapply( seq_len(nSims), function(sim){ gamma1 <- rgamma(x["m"], x["sp(skewness1.5)"], x["scp1"]) gamma2 <- rgamma(x["n"], x["scp1"], 1) gamma1 <- gamma1 -

Dear list: I have a data frame with student name, class he attended and marks for subjects he attended. Students took second exam if they performed badly in their first attempt. I want to consider the test scores where they obtain highest median. there are 6 classes. As a sample case, I will consider only classes A, B and C. For class A, Student Raj took first exam and he did not score well.

When attempting to merge 3 data frames, one of which has fewer columns than the others, rbind.data.frame correctly refuses to perform the bind. However, the error message given is a bit obscure due to a logical bug in the match.names() internal function to rbind.data.frame. Illustration: ## Three data frames with same column variable names: > foo <- data.frame(v1 = c('a',

Hi! The problem is that the test environment inherits from the global environment. See https://github.com/hadley/testthat/blob/master/R/test-files.r The students labs are simply an R script file. Say that they have an assignment to calculate sqrt(2) and store it in variable a. In the same session they should be able to test the script file when they are done (using a function mark_my_file() in

Hi, i am sorry, the output should be values between 0 and 0.1 and not supposed to be 1.00, it is because they are type 1 error rate. And now i get output 1.00 for several samples,rhis is no correct. The loop do not run for every row. i do not know where is my mistake. As i use the same concept on normal distribution setup, i get the result. Sent from my phone On Thierry Onkelinx

i have combined all the variables in a matrix, and i wish to conduct a simulation row by row. But i found out the code only works for the every first row after a cycle of nine samples. But after check out the code, i don know where is my mistake... can anyone pls help .... #For gamma disribution with equal skewness 1.5 #to evaluate the same R function on many different sets of data

Always keep the mailing list in cc. The code runs for each row in the data. However I get the feeling that there is a mismatch between what you think that is in the data and the actual data. ir.

In my versions of these standard R functions I either add options or alter some defaults that seem to create difficulties for most of my students -- for example, when they do
