geometricmean_bynameR Documentation

Name- and element-wise geometric mean of two matrices.


Gives the geometric mean of corresponding entries of a and b.


geometricmean_byname(..., .summarise = FALSE)



operands; constants, matrices, or lists of matrices


Tells whether the operation should be accomplished across lists (FALSE) or down lists (TRUE).


This function performs a union and sorting of row and column names prior to performing geometric mean. Zeroes are inserted for missing matrix elements.
