Suppose I have a matrix, , "in r, we have a=matrix(1:4,nrow=2)"
I define another vector (1,2,3), "in r, we have b=c(1,2,3)"
I have set up a for loop,
"new=NULL
for (i in 1:length(b))new=c(new,a+b[i])"
I obtain new= 2 3 4 5 3 4 5 6 4 5 6 7, this return me with a vector.. but I want a matrix
So I convert by coding,
"for (i in 1:3) {c[i]=matrix(new[(1+4*(i-1)): (4+4*(i-1))],nrow=2)}"
in hope that my c[1] equals , c[2] equals and c[3] equals ,
However I received an error, what's wrong with the above code?
(Note the code is working fine if I use for (i in 1:3) {print(matrix(new[(1+4*(i-1)): (4+4*(i-1))],nrow=2))} to print the result, but I can't seem to allocate the matrix to c[i] )
