| dim_and_names {GPUmatrix} | R Documentation |
Number of rows and columns and its corresponding names
Description
These functions mimic the 'base' functions rownames, colnames, dimnames, dim, length, ncol, nrow to operate on gpu.matrix-class objects.
The "dim family functions" set or get the dimension of a gpu.matrix-class object.
The "rownames and colnames family functions" set or get the corresponding names of rows and columns of a gpu.matrix-class object.

Value
rownames returns the names of the rows of a gpu.matrix-class object.
colnames returns the names of the columns of a gpu.matrix-class object.
dim returns the number of rows and columns of a gpu.matrix-class object and
dim <- sets the number of rows and columns of a gpu.matrix-class object.
dimnames returns the names of the rows and columns of a gpu.matrix-class object and
dimnames <- sets the names of the rows and columns of a gpu.matrix-class object.
length returns the length (ncol*nrow) of a gpu.matrix-class object.
ncol returns the number of columns of a gpu.matrix-class object.
nrow returns the number of rows of a gpu.matrix-class object.

Examples
## Not run:
a <- gpu.matrix(rnorm(9))
dim(a) <- c(3,3) #sets the number of rows and columns.
dim(a) #shows the number of rows and the number of columns
ncol(a) #shows the number of columns
nrow(a) #shows the number of rows
length(a) #shows the lenght of the matrix (nrow*ncol)
dimnames(a) <- list(c("r1","r2","r3"),c("c1","c2","c3")) #sets rows and column names
dimnames(a) #shows both the row and the col names
#these functions are equivalent to the following:
rownames(a) <- c("r1","r2","r3") #adds rownames to a.
colnames(a) <- c("c1","c2","c3") #adds colnames to a.
rownames(a) #shows rownames.
colnames(a) #shows colnames.
## End(Not run)
