Rcim | R Documentation |
Rearrange the rows and columns of the input so that the first row and first column are baseline. This function is for rank-zero row-column interaction models (RCIMs; i.e., general main effects models).
Rcim(mat, rbaseline = 1, cbaseline = 1)
mat |
Matrix, of dimension r by c. It is best that it is labelled with row and column names. |
rbaseline, cbaseline |
Numeric (row number of the matrix |
This is a data preprocessing function for rcim
.
For rank-zero row-column interaction models this function
establishes the baseline (or reference) levels of the matrix
response with respect to the row and columnsâ€”these become
the new first row and column.
Matrix of the same dimension as the input,
with rbaseline
and cbaseline
specifying the
first rows and columns.
The default is no change in mat
.
This function is similar to moffset
; see
moffset
for information about the differences.
If numeric, the arguments
rbaseline
and
cbaseline
differ from arguments
roffset
and
coffset
in moffset
by 1 (when elements of the matrix agree).
