Hi,
I am having some problems using the if statement correctly. I have used it
many times previously so I dona't know what is different with this case.
Here is my problem:
I have a 1X10 matrix of values as follows:
> H.MC
[,1]
[1,] 4.257669
[2,] 7.023242
[3,] 4.949857
[4,] 5.107000
[5,] 4.257669
[6,] 4.257669
[7,] 4.257669
[8,] 4.257669
[9,] 4.257669
[10,] 4.257669
What I want to do is replace all the values if 4.257669 with a random number
between 3 and 4.5. To do this I have:
H.MC.fin <- matrix(0,10,1)
for (j in 1:10) {
if(H.MC[j] == 4.257669) H.MC.fin[j] <-runif(1,3,4.5) else H.MC.fin[j] <-
H.MC[j]
}
This doesn't seem to do anything and H.MC.fin is the same as H.MC.
Does anyone know what I am doing wrong?
Thanks,
Doug
