Hi:
If you want the literal character strings, this works:
x<-c(1, 2, 3)
> y<-c(4,5,6)
> outer(x, y, function(x, y) paste('(', x, ',', y, ')', sep = '') )
[,1][,2][,3]
[1,] "(1,4)" "(1,5)" "(1,6)"
[2,] "(2,4)" "(2,5)" "(2,6)"
[3,] "(3,4)" "(3,5)" "(3,6)"
However, I have the sense y
Hi,
First, create a MATRIX of the correct size:
xy <- matrix(nrow=3, ncol=3)
Then, in your for loop, you need to index each cell correctly, like this:
xy[i,j]
Finally, if you want to assign "1,4" to each cell, you need to paste
x[i] and y[j] together, like this:
xy[i,j]<-paste(x[i],y[j], sep=
Try
x1<-matrix(1,3,1)%x%x
y1<-y%x%matrix(1,3,1)
Z<-cbind(x1,y1)
And later you need to move towards list and matrix

Hello,
I have two data.
x<-c(1, 2, 3)
y<-c(4,5,6)
How do i create matrix of 3 by 3 from this two, such that
(1,4) (1,5) (1,6)
(2,4) (2,5) (2,6)
(3,4) (3,5) (3,6)
I tried some thing like this:
xy <- as.data.frame(c(0,0,0), dim=c(3,3))
for(i in 1:3)
for(j in 1:3)
xy[i][j]<-c(x[i
5 matches
