Hi, Maybe I have not been looking in the right spot, but, I have not been able to fine a command to automatically calculate the running cumulative sum of a vector. Is there such a command?
Example of current code: > eig$values [1] 678.365651 6.769697 2.853783 > prop<-eig$values/sum(eig$values) > prop [1] 0.986012163 0.009839832 0.004148005 > cum<-c(prop[1],sum(prop[1:2]),sum(prop[1:3])) > cum [1] 0.9860122 0.9958520 1.0000000 This works, but, if the length of the vector changes I have to manually change the code.
