Dear All: I am trying to use the R function "svm" with "type =C-classification" , but I got the following error message SVM.Model1 <- svm(type ~ ., data=my.data.x1x2y, *type='C-classification'*, kernel='linear',scale=FALSE) *Error in eval(predvars, data, env) : object 'type' not found* I am wondering if I should install a specific R

Dear All: It was saved, but there was a space somewhere. So it works for me now. I do have another similar problem.

Dear All: good morning I am trying to graph the function y=f(x)=1/x over the interval (-5,5). But I am getting an error message. Please see below. I am getting the error message: *Error in xy.coords(x, y, xlabel, ylabel, log) : * * 'x' and 'y' lengths differ* x x <- seq(-5, 5, 0.01) y < 1/x plot(x,y, type='l', xlim=c(-5, 5), ylim=c(-5, 5), xlab = "x",

Dear All: One more thing. I want to add the normal curve to the histogram. Is there away to stretch the peak of the curve to the top of the histogram or at least near to the top of the histogram.

The object you load has the same name as the object you saved. In this case datahs0csv and not the name of the file sans .rda On Di., 12.

Dear All: I am wondering if there is a way in R to draw these two circles with shaded tracks in both circles using R, and make both circles uncovered. I am trying to make it in MS words, but I could not. Your help will be highly appreciated. In my previous post I added the image of the two circles, but the post never published. I just thought to resent the post again without the image. with
