Re: [R] question for loop on matrix row level.

[Spencer Graves]

Have you considered making "aval" an array with the same number of 
columns as "matrixname"?  Try the following:

aval <- array(NA, dim=c(2,2))
for(i in 1:2){
        matrixname <- array(i+(1:4), dim=c(2,2))
        aval[i,] <- matrixname[1,]
}
aval
hope this helps.  spencer graves

For the 1000 simulations, a matrix will be generated
each time. And, I need to choose the first row of the
generated matrix. The following loop doesn't work
though:
for (i in 1:1000) {

aval[i]<- matrixname[1,]

}

Any solution? thanks!
