Como projetar um novo vetor no espaço PCA?
Depois de executar a análise de componentes principais (PCA), quero projetar um novo vetor no espaço do PCA (ou seja, encontrar suas coordenadas no sistema de coordenadas do PCA). Eu calculei o PCA na linguagem R usando prcomp. Agora eu devo poder multiplicar meu vetor pela matriz de rotação PCA....
