[R] rpart Error in yval[, 1] : incorrect number of dimensions
I tried using rpart, as below, and got this error message "rpart Error in yval[, 1] : incorrect number of dimensions". Thinking it might somehow be related to the large number of missing values, I tried using complete data, but with the same result. Does anyone know what may be going on, and how to fix it? I have traced two similar error messages in the Archive, but following the threads did not make it clear how to fix the problem.> currwh.rpart<-rpart(formula = CURRWHEE~EA17_6_1 + EA17_9_1 + X087 + X148 + X260 + MOTHERSA + GESTATIO,method="class")>> currwh.rpartn=6783 (2283 observations deleted due to missing) node), split, n, loss, yval, (yprob) * denotes terminal node 1) root 6783 720 3 (0.1060002949 0.8938522778 0.0001474274) *>> summary(currwh.rpart)Call: rpart(formula = CURRWHEE ~ EA17_6_1 + EA17_9_1 + X087 + X148 + X260 + MOTHERSA + GESTATIO, method = "class") n=6783 (2283 observations deleted due to missing) CP nsplit rel error 1 0 0 1 Error in yval[, 1] : incorrect number of dimensions>[[alternative HTML version deleted]]
