Share 'Question about R error: 'all arguments must have the same length''
i am using R to fit svms using the e1071 package. Everything seems fine when i train the model, and even when validating with a different data-set. the training data-set has 1500 records and 17 variables. When i attempt to generate a classification matrix i obtain the following error:
“Error in table(pred = prediction, true = observed) : all arguments must have the same length”
