Hello,
&nbsp;

I want to sum first three terms of each column of matrix. But I don't calculate with "apply" function.
&nbsp;

skwkrt&lt;-function(N=10000,mu=0,sigma=1,n=100, nboot=1000,alpha=0.05){
x&lt;-rnorm(N,mu,sigma)#population
samplex&lt;-matrix(sample(x,n*nboot,replace=T),nrow=nboot) #...
}
&nbsp;

is that: suppose a is a 5x2 matrix.
&nbsp;a={1,2,3,4,5
6,7,8,9,10}
&nbsp;

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!!!
