How to assign a vector to a variable in Jags?
- How do I assign a vector to a variable in JAGS?
For example,
```
pi[] <- [Beta1, Beta2, Beta3]
pi <- [Beta1, Beta2, Beta3]
```
are both invalid in JAGS, yielding the error:
```
Error parsing model file:
syntax error on line ... near "["
```
One option is just to assign the values one row at a time:
```
pi[1] <- Beta1
pi[2] <- Beta2
pi[3] <- Beta3
```
Another option in the above case is to make Beta1, Beta2, and Beta3 a vector to begin with: e.g., Beta[1], Beta[2], and Beta[3]. Then it is possible to to assign the whole vector at once.
```
pi <- Beta
```
This even removes the need for pi in my particular case.
