ROCR . visualizing classifier performance in R, with only 3 commands. Please support our work by citing the ROCR article in your publications: Sing T, Sander O, Beerenwinkel N, Lengauer T. [2005] ROCR: visualizing classifier performance in R. Bioinformatics 21(20):3940-1 ROCR only accepts the alpha version as input (e.g. = 0:5). If no value for alpha is given, If no value for alpha is given, the mean will be balanced by default Comme le soulignent d'autres, le problème est que la prévision dans ROCR attend des valeurs numériques. Si vous insérez des prédictions de randomForest (en tant que premier argument de la prédiction dans ROCR), cette prédiction doit être générée par type='prob' au lieu de type='response', qui est la valeur par défaut.Vous pouvez également utiliser les résultats de type.

I particularly like the way the performance() function has you set up calculation of the curve by entering the true positive rate, tpr, and false positive rate, fpr, parameters.Not only is this reassuringly transparent, it shows the flexibility to calculate nearly every performance.

Other packages, such as the pROC package, can be useful for many functions and analyses, especially testing the difference between ROC and pROC curves. In some ways, you may want to use proc admissibly over ROCR, especially because (when I checked Dec 18, 2014) the ROCR package was orphaned. But if you are working in ROCR, I hope this give you.

Some R Packages for ROC Curves · R View

A small introduction to the ROCR package R-blogger

From: Uwe Ligges <ligges_at_statistik.tu-dortmund.de> Date: Fri, 27 Feb 2009 17:21:57 +0100. For question 1: Can you please report to the package maintainer (well, I am CCing Tobias now) who will certainly be happy to improve the package (particularly the demo behaviour) I have some models, using ROCR package on a vector of the predicted class percentages, I have a performance object. Plotting the performance object with the specifications tpr, fpr gives me a ROC curve. I'm comparing models at certain thresholds of false positive rate (x). I'm hoping to get the value of the true positive rate (y) out of the performance object. Even more, I would like to. The ROCR package can plot multiple ROC curves on the same plot if you plot several sets of predictions as a list.. The prediction() function takes as input a list of prediction vectors (one per model) and a corresponding list of true values (one per model, though in our case the models were all evaluated on the same test set so they all have the same set of true values) # ROCR currently supports only evaluation of binary classification tasks. Por desgracia, se produce un problema diferente que está más allá del alcance de esta pregunta. Muchas gracias por una explicación detallada. Yo era capaz de utilizar ROCR para la clase 2 con su ayuda y tratar de averiguar cómo conseguir alrededor de >2 clase de problema. Feliz de ayudar. Si la respuesta resuelve tu.
