Hi,
I have problem with my R program. Actually, it just a simple program, but I do
not know the error is. Here is part of my program:
....
if (tau2ca==0) {MVvc <- 0.01} else {MVvc <- tau2ca}
ri_vc <- si2/MVvc
vi_vc <- ri_vc + 1
Y_bar_vc <- sum(y/vi_vc)/sum((1/vi_vc))
tau2MVvc <- sum((1/vi_vc)*(y - Y_bar_vc)^2)/(k-1)
....
But then, there is an error displayed in workspace
Error in if (tau2ca == 0) { : missing value where TRUE/FALSE needed
I do not know why there is an error like that. I think I type the program
correctly. Also, I just want to make sure whether my program below is right or
not.
for (l in 1:k)
{if (a[l]==0 | b[l]==0 | c[l]==0 | d[l]==0)
{ a[l] <- a[l]+0.5
b[l] <- b[l]+0.5
c[1] <- c[1]+0.5
d[1] <- d[1]+0.5
}
}
Looking forward to hearing from you.
Many thanks,
