[R] ROC curve in R
Hi, i have a fairly large amount of genomic data. I have created a dataframe which has Reference as one column and Variation as another. I want to plot a ROC curve based on these 2 columns. I have serached the R manual but I could not understand. Can anybody help me with the R code for plotting ROC curve.

Not sure what sort of R manual you consulted, but surely any basic introduction must have covered how to search. In the interest of moving you a bit faster perhaps: ?RSiteSearch -- David Winsemius, MD West Hartford, CT __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.

Did you try googling on R ROC function (or something similar) or using the RSiteSearch() function? ?RSiteSearch RSiteSearch(ROC,restr=func) Learn to use R's various search capabilities before posting, please!
