Re: [R] ROCR package question for evaluating two regression models

Hi Andra, I have been doing some ROC analysis for a new diagnosis test. I used the pROC package to assess thresholds and compare different diagnosis tests to a "gold standard". In your case, let say the gold standard are the observed values y0. Here is an example: y0 <- sample(0:1,50,replace=TRUE

[R] Read data in sequences

Dear R users, I tried to find a solution in the search list, but I cannot find it. I would like to read a .txt file with, let say, three variables, with two of which have repeated values in a number a columns. An example: The variables: Treat, x1, x2. The values: A 2.5 3.4 2.7 5.6 5.7 5.4 10.1
