...mmand set language='en'. I would like to plot ROC curves. I have a serie of 10 threshold tests that i do for 10 patients. The prediction for the patients is always the same but the status can change given to the considered threshold. I have 11 columns of 10 rows, the first colums containing the10 lines of the predicted status of the patients (0=cured, 1=non cured). Then follow 10 columns (10 thresholds) containing the found status using the threshold. Please do someone know how i can use those values with R to plot ROC curves? I thank you for your understanding, Josiane. "Everythin...

Dear R-Experts, Here below my R code working but I don't know how to complete/finish my R code to get the final plot with the extrapolation for the10 more years. Indeed, I try to extrapolate my data with a linear fit over the next 10 years. So I create a date sequence for the next 10 years and store as a dataframe to make the prediction possible. Now, I am trying to get the plot with the actual data (from year 2004 to 2018) and with the 10 more...

Hi R folks, I am using R version 2.2.1 for Unix. I am exploring the rpart function, in particular the rpart.control parameter. I have tried using different values for xval (0, 1, 10, 20) leaving other parameters constant but I receive the same tree after each run. Is the10 fold cross-validation default still running every time? I would expect the trees to change at least a little when I change the number of folds in the cross-validation but this is not the case in my tests. Any advice would be greatly appreciated. Thanks, -- Brian Sanborn brian at ndr.com
