Hello Can someone help me with the following, specifically in judging whether a matrix exists. I have trouble with the first line below. In this case, matrix obj$hessian exists and is 74 x 74. I receive the error message: Warning message: In all(w$hessian) : coercing argument of type 'double' to logical Thank you all. --- if (!all(obj$hessian)|OPG){ vb<-obj$gradientObs;

I need to have all elements of a matrix multiplied by a weight before being post-multiplied by itself, as shown in the forst block of codes below. I can also multiply the matrix by the square root of the weight and then take the outer product. Actually, what I need is this. Denote each row of the matrix by a row vector as xi and each element of the weighting vector as wi. Then, I need the

I am running R-3.0.3 on RStudio 1.1.183. I have recently gotten the following error message while saving an .RData file with the save.image command. I have not had this problem until recently. Help appreciated. === Error in save.image("bope1a.RData") : image could not be renamed and is left in bope1a.RDataTmp [[alternative HTML version deleted]]

The RStudio list generally does not respond to free version users. I was hoping someone one this (R) list would be kind enough to help me.
