I would like to ask help on distance measures for continuous variables
There is an example:
x1 = (0,0)
x2 = (1,0)
x3 = (5,5)
The example is to find the distance matrix for L1-norm and L2-norm(Euclidean). I don't know how to compute in R to get the following answer:
I have tried to do it like this but it didn't work as expected.
y2 <- c(0,0)
y3 <- c(1,0)
y4 <- c(5,5)
y5 <- rbind(y2,y3,y4)
dist(y5)
y2 <- c(0,0)
y3 <- c(1,0)
y4 <- c(5,5)
mat <- rbind(y2, y3, y4)
d1 <- dist(mat, upper=TRUE, diag=TRUE, method="manhattan")
d1
# y2 y3 y4
# y2 0 1 10
# y3 1 0 9
# y4 10 9 0
d2 <- dist(mat, upper=TRUE, diag=TRUE)^2
d2
# y2 y3 y4
# y2 0 1 50
# y3 1 0 41
# y4 50 41 0
