ds.matrixDimnames | R Documentation |
Adds the row names, the column names or both to a matrix on the server-side.
ds.matrixDimnames(
M1 = NULL,
dimnames = NULL,
newobj = NULL,
datasources = NULL
)
M1 |
a character string specifying the name of a server-side matrix. |
dimnames |
a list of length 2 giving the row and column names respectively. An empty list is treated as NULL. |
newobj |
a character string that provides the name for the output
variable that is stored on the data servers. Default |
datasources |
a list of |
This function is similar to the native R dimnames
function.
Server function called: matrixDimnamesDS
ds.matrixDimnames
returns to the server-side
the matrix with specified row and column names.
Also, two validity messages are returned to the client-side
indicating the new object that has been created in each data source and if so whether
it is in a valid form.
