Dear All, When bootstrapping a statistics based on more than one vector, from a data.frame or a matrix object, it looks like I am not able to pass the data to R. What am I doing wrong? I use the library "bootstrap". Here is an example with a data.frame called "data" "boot2_bootstrap(data, theta, nboot) I get the following error message: Error in inherits(x,

Dear All, I am trying to visualize the surface of a bivariate kernel density estimate. I have a vector of bivariate observations(x,y), and a function which computes the kernel density estimate z corresponding to each observation. I cannot generate the (x,y) data in the ascending order needed by persp(x,y,z). I was wondering whether there is an R version of the S function interp. Would anybody
