If you have created an object X which is an object of class "ppp", and
you have a vector x which you wish to be the marks of X, just do

	marks(X) <- x

The vector x should be either numeric or a factor, and should be of length
equal to the number of points in the point pattern X.

I your particular case I think that (something like)

	temp <- readOGR(".","C67mF_K)
	C67mF_K <- as(temp,"ppp")
	marks(C67mF_K) <- temp at data$typ

should work.
