correlation between a reduced space and the original space
Calculates the correlation between distances in a reduced space and the original space
PCdist(PCs, PCscores, x = 5, plot.type = "b")
PCs |
m x k matrix of Principal Components where m is the k is the number of PCs. |
PCscores |
n x m matrix of Principal Component scores where n is the number of observations. |
x |
integer: increment for every x-th PC the subspace to fullspace correlation will be calculated. |
plot.type |
"b"=barplot of correlation values, "s"=line between correlation values. |
a vector of R-squared values between subspace and fullspace distances and a barplot depicting the correlations belonging to the subspace.
