| fm.mapply2 | R Documentation |
fm.mapply2 applies FUN to the first elements of each
vector/matrix, the second elements, the third elements, and so on.
Two vectors/matrices should have the same shape. Currently,
fm.mapply2 only accepts predefined basic operators returned
by fm.get.basic.op.

o1, o2 |
a FlashR vector/matrix. |
FUN |
the reference or the name of one of the predefined basic binary operators. |
set.na |
a logical value indicating whether to set the value in the output matrix to NA if the value in the corresponding location of the input matrix is NA. |
fm.mapply.row and fm.mapply.col applies to a matrix and
a vector. fm.mapply.row applies FUN element-wise to
each row of the matrix in the left argument and the vector in the right
argument. fm.mapply.col applies FUN element-wise to
each column of the matrix in the left argument and the vector in the right
argument.
a FlashR vector/matrix.
