Dear R users,
I am using a loop that does matrix multiplication in a manner
(A%*%B)%*%(A)
Here A is a row of data frame D of order(200x4). B is a (4x4). No need to say D[j,] is 1x4
so I am using
for(j in seq(0.1,20,by=0.1)){
S<- (D[j,]%*%B)%*%(D[j,])
print(S)
}
As a result I am geting only one value of S, which comes using j=20.
I need all 200 values of S so that I can use that for further analysis. Means I need a 200x1 column.
Any help will be appreciated.
Thanks,
