Hello all,

I am very new to R and i am facing two problems. First i didn't succeed changing the konsole language in english even after trying the line command 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.
