Convert an Array with 4 Dimensions into a MatrixFlorian Gerber
converting a data.table object to a matrix is not a difficult job. We just need to use as.matrix function and store the data.table object into a new object that will belong to the matrix, otherwise R will not be able to convert the data.object to a matrix. For example, if we have...
If you were able to convert it into a matrix, the matrix would have to be 테마복사 [ '27.41058128992816'; '27.39301824439'; '27.3953145167'] However, that would not be a legal matrix in MATLAB because the number of columns would not be consistent. Might I suggest that what you ...

Good to know that there is an efficient transpose though, I wasn't sure if this would be the case given R's memory semantics. However, in other cases (e.g., matrix multiplication), dgRMatrix objects are explicitly converted to dgCMatrix I wonder how common this is. I would hope dgR...
