| rwiot-utils {rrcov} | R Documentation |
Different utility functions to be used in rrcov and packages depending on rrcov:
myscreeplot Plots screeplots for two covariance matrices
mtxconfusion Computes a confusion matrix between actual and predicted class membership
MATLAB-like functions
sqrtm Returns the square root of a symetric positive definite matrix
ones Returns a nxp matrix filled with ones
zeros Returns a nxp matrix filled with zeros
vecnorm Returns the norm of a vector
rankMM Returns the rank of the matrix
repmat Replicates a matrix
myscreeplot(rcov, ccov)
mtxconfusion(actual, predicted, prior = NULL, printit=FALSE)
sqrtm(A)
rankMM(A, tol = NULL, sv = svd(A, 0, 0)$d)
ones(n=1, p=1)
zeros(n=1, p=1)
repmat(A, n, p)
A |
A matrix. |
tol |
Optional numerical tolerance (compared to singular values). |
sv |
A vector of non-increasing singular values of a matrix A, if already computed. |
rcov, ccov |
Covariance matrices. |
n |
Number of rows. |
p |
Number of columns. |
actual |
Actual class membership. |
predicted |
Predicted class membership. |
prior |
Prior probabilities. |
printit |
Wheather to print the results. |
