Hence, it means the matrix should be numeric. R is the key that opens the door between the problems that you want to solve with data and the answers you need to meet your objectives. level, they can use gofilter function. Gage R&R studies can be conducted on both variable data (measurements that can be displayed in decimal form), and attribute data (produces “go/no-go” results or a count of defects). The process is not capable of meeting specifications. Your only alternative, at this time, is to perform 100% inspection of the parts and separate the parts that are within specifications from those that are out of specifications. If set to TRUE, gives a more verbose increasing "granularity", i.e. Only used if method="randomForest".
