Subject: other way of making a table?
I'm making tables for prediction results of classifiers (2 classes) that show the usual numbers, true positives, false positives, etc
I used the command
table(predictedLabels,realLabels)
to make those.
I just had a case though ,where one of the label vectors had only one class in it. This will result in only half a table.
Compare:
x<-c(1,1,1,0,0)
y<-c(1,1,1,0,1)
table(x,y)
to
x<-c(1,1,1,0,0)
y<-c(1,1,1,1,1)
table(x,y)
I want the second one to still have all 4 cases (second column all zeros then).
Any easy solutions?
