Hello,
I want to sum first three terms of each column of matrix.
But I don't calculate with "apply" function.
skwkrt<-function(N=10000,mu=0,sigma=1,n=100,
nboot=1000,alpha=0.05){
x<-rnorm(N,mu,sigma)#population
samplex<-matrix(sample(x,n*nboot,replace=T),nrow=nboot)
#...
}
is that: suppose a is a 5x2 matrix.
a={1,2,3,4,5
6,7,8,9,10}
I want to sum first three terms.
sm[1]=1+2+3
sm[2]=6+7+8
But I don't calculate. please help me!!!
