A simple function to produce an ROC curve from a known edge matrix and a posterior edge probability matrix.
1 | linesROC(trueMatrix, pep, col = "red", lty = 1, lwd = 1)
|
trueMatrix |
The 'true' edge matrix. |
pep |
A matrix of posterior edge probabilities. |
col |
A colour (passed to segments). |
lty |
A line type (passed to segments). |
lwd |
A line width (passed to segments). |
The area of the ROC curve is also sent to the console.
The area of the ROC curve.
