km is used to fit kriging models when parameters are unknown, or to create km objects otherwise. In both cases, the result is a km object. If parameters are unknown, they are estimated by Maximum Likelihood., Tests if the names of a second matrix are equal to a given matrix up to a permutation, and permute its columns accordingly. When the second one has no column names, the names of the first one are used in the same order. checkNames(X1, X2, X1.name = "X1", X2.name = "X2") checkNamesList(X1, l2, X1.name = "X1", l2.name = "l2") X1, The difference between the width of # SK and UK intervals are due to the estimation error of the trend parameters # (but not to the range parameters, not taken into account in the UK formulae). p.SK <- predict (model, newdata=data.frame (x=t), type="SK") lines (t, p.SK$mean, type="l", ylim=c (-7,7), xlab="x", ylab="y") lines (t, p.SK$lower95 , km is used to fit kriging models when parameters are unknown, or to create km objects otherwise. In both cases, the result is a km object. If parameters are unknown, they are estimated by Maximum Likelihood., I need to pick top 3 values from each column of a matrix using R and populate the values to a holder (another matrix). While trying to do this, I am getting an error as : Error in t.default (head (n, 我试图将DiceKriging包中的km函数应用到多变量数据集中。 当我使用我的整个数据集 (维度= 938,13)时,算法没有问题地运行。 当我使用这个数据集的一个较小的子集 (维度= 94,13)时,我遇到了以下错误: Error in t.default(T) : argument is not a matrix. 在分析数据子集时,我不确定是什么导致了这个错误。 作为参考,下面是我正在运行的数据和代码:.
