accuracy(actual, predicted, rank)
confusionTable(actual, predicted, rank)

Arguments

actual

data.frame with the actual classification hierarchy.

predicted

data.frame with the predicted classification hierarchy.

rank

rank at which the accuracy should be evaluated.

Value

seq <- readRNAStringSet(system.file("examples/RNA_example.fasta",
	package="rRDP"))

### decode the actual classification
actual <- decode_Greengenes(names(seq))
  
### use RDP to predict the classification
pred <- predict(rdp(), seq)  

### calculate accuracy
confusionTable(actual, pred, "genus")  
accuracy(actual, pred, "genus")
