Preimage {chickn} | R Documentation |
Consensus chromatogram computation.
Preimage( Data, K_W1, C_out, Cl_assign, max_Nsize = 32, ncores = 4, DIR_out = getwd(), BIG = FALSE )
Data |
A Filebacked Big Matrix n x N. Data signals are stored in the matrix columns. |
K_W1 |
A Filebacked Big Matrix of the Nystrom kernel matrix s \times N, where N is the number of signal in the training collection and s is the Nystrom sample size. |
C_out |
A Filebacked Big Matrix of cluster centroids. |
Cl_assign |
A Filebacked Big matrix of the cluster assignment. |
max_Nsize |
Maxumum number of neighbors. |
ncores |
Number of cores. |
DIR_out |
A directory to save the result, by default it is the working directory. |
BIG |
logical parameter that controls whether the resulting consensus chromatograms are stored as a Filebacked Big Matrix ('Centroid_preimage.bk'). Default is FALSE. |
A matrix or a Filebacked Big Matrix if BIG
= TRUE.
