Dear Group,
I have the following matrix
m
[,1] [,2] [,3] [,4] [,5] [,6] [,7] [,8]
[1,] 0 2 1 Inf Inf Inf Inf Inf
[2,] 1 0 2 Inf Inf Inf Inf Inf
[3,] 2 1 0 Inf Inf Inf Inf Inf
[4,] 3 2 1 0 Inf Inf Inf Inf
[5,] Inf Inf Inf Inf 0 Inf Inf Inf
[6,] Inf Inf Inf Inf 1 0 Inf Inf
[7,] Inf Inf Inf Inf Inf Inf 0 Inf
[8,] 1 3 2 Inf Inf Inf 1 0
I want all values grater than 0 = to 1 and zero other wise?
thanks in advance
so
this used,
m <-ifelse( (m==0)|| is.infinite(m),0, 1 )
but it gave me zero result
replacing
|| with | ,make sense and return the matrix I was looking for.
what is the difference betwen boht || an | ? when to use each ?
|| only for scalars, see the documentation.
From your text you want something different:
m[m>0] <- 1
but your code says you want to replace Inf by 0?
Best,
Uwe Ligges
thanks in advance
