Después de realizar el análisis de componentes principales (PCA), quiero proyectar un nuevo vector en el espacio PCA (es decir, encontrar sus coordenadas en el sistema de coordenadas PCA).
He calculado PCA en lenguaje R usando prcomp
. Ahora debería poder multiplicar mi vector por la matriz de rotación PCA. ¿Deben los componentes principales de esta matriz estar dispuestos en filas o columnas?
