Hello All, I have a series of steps that needs to be run many times. Hence I put them all into a function. There is no problem in function creation, but when I call the function, the steps are not getting executed or only the first step gets executed. What possibly could be the reason? Sample Function and the result: fun <- function () { # Package load into R; a <-

Hi users! I am fitting a model with several factor variables as independents using svm. since there are lots of categorical variables,the training and test data sets have been created using dummy.data.frame option from dummies package. I have a factor A in the training data set with 2 levels (0,1).In the test set, this factor A has only 1 level (1) and hence when applying dummy.data.frame, the

Hi, I am new to R and here is what I am doing in it now. I am using machine learning technique (svm) to do predictive modeling. The data that I am using is one that is bound to grow perpetually. what I want to know is, say, I fed in a data set with 5000 data points to svm initially. The algorithm derives a certain intelligence (i.e.,output) based on these 5000 data points. I have an additional

Hello, I am trying to use SVM from e1071 package for doing binary classification and I am having problems in prediction using SVM. I ran a SVM for X~as.factor(X1)+as.factor(X2)+as.factor(X3),data=data1,cross=10. str(data1) gives me data.frame': 5040 obs. of 5 variables: $ X4: int 1 2 3 4 5 6 7 8 9 10 ... $ X : int 0 1 0 1 0 0 1 1 1 1 ... $ X2: int 1 8 15 18 1 14 10 9 8 8 ... $ X3
