Create rownames for a contrast matrix using the coefficients and the names of the coefficients. The rownames will be [value * name] == null, e.g. [beta + 4*alpha] = 0.
.contrast2name(contrast, null = NULL)
[matrix] a contrast matrix defining the left hand side of the linear hypotheses to be tested.

a character vector.
When argument NULL
is null then the rownames will not be put into brackets and the right hand side will not be added to the name.
