m2c {ffmanova} | R Documentation |
Functions to convert a matrix to a list of partitioned matrices, and back again.
m2c(M, df = rep(1, dim(M)[2])) c2m(CC) c2df(CC)
M |
matrix to be partitioned according to df |
df |
integer vector. See Details |
CC |
list of matrices, typically the output of m2c |
m2c
partitions a matrix into a list of matrices, by putting the
first df[1]
coloumns into the first matrix, the next
df[2]
coloumns into the second, etc.
c2m
joins a partitioned matrix back into a single matrix.
c2m(m2c(X, df))
equals X
.
c2df
takes a list of matrices and returns a vector with the
number of coloumns of the matrices.
m2c
returns a list of matrices.
c2m
returns a matrix.
c2df
returns a numeric vector.
sum(df)
must equal ncol(X)
.
