Try this. As you did not supply a reproducible example my code is untested:
1.m.vector[index.vector] <- NULL
or
new.1.m.vector <- 1.m.vector[- index.vector]
Someting equivalent is possible for the matrix.

Dear all,
I have a numeric vector that contains indices.
I also have two matrices of [1,m] dimension and of [m,n] dimension.
I want for every indexto remove the current element from the [1,m] vector an
the row from the [m,n] matrix.
How I can do that efficiently in R? So to say not have a for loop getting
parameter after parameter and then removing row by row from the vector and the
matrix.
I would like to thank you in advance
