Dear Group,
Kindly,
I have those two lines
if( (z_nebla==0) || (z_nebla_dash==0) )
CM <- 0 else
CM <- 0.5 *(1/a) + 0.5*(1/b)
when running it
I got this
z_nebla==0)
logical(0)
> (z_nebla_dash==0)
logical(0)
> (z_nebla==0) || (z_nebla_dash==0)
[1] NA
why (z_nebla==0) || (z_nebla_dash==0)
gives me NA ?
thanks in advance
Ragia
