1. 为什么会出现R语言的“incorrect number of dimensions”错误? 当你在R语言中操作数组、矩阵或数据框时,如果你的代码尝试使用错误的维度访问它们,就会出现"incorrect number of dimensions"错误。这通常是由于代码中的索引错误或数据结构错误导致的。 2. 如何解决R语言中的“incorrect number of dimensions”错误?
当出现"incorrect number of dimensions"错误时,R语言会提示我们在操作数组、矩阵或数据框时维度数量不正确。该错误通常是由于我们尝试将具有不匹配维度的对象进行操作所导致的。 代码示例 下面是一个简单的代码示例,演示了"incorrect number of dimensions"错误的产生: # 创建一个矩阵mat<-matrix(1:9,nrow=3,ncol=...
错误原因 在R语言中,数据通常以不同的对象类型存储。例如,向量、矩阵、数据框等都是常见的对象类型。这些对象具有特定的维度(dimension),例如向量是一维的,矩阵是二维的,数据框可以是一维或二维的。当你尝试在不匹配维度的对象上执行操作时,就会出现“incorrect number of dimensions”错误。 例如,假设你有一个一维向...

However, the number of bins for which we must estimate probabilities explodes quickly in six dimensions when compared to the number of observations (residue pairs) in the training set. Thus we choose to treat some lines of evidence as independent, modeling the joint distribution ...
