title: This seems to work fine but keep having "command #Bugs:gen.inits cannot be executed (is greyed out)"
body: <p>I am doing a simple regression model with WinBUGS via R2WinBUGS.
  Results appear ok, however WinBUGS keeps showing this line and I don't know why:</p>
  
  <pre><code>command #Bugs:gen.inits cannot be executed (is greyed out)
  </code></pre>
  
  <p>Does someone have an idea?
  Thanks!</p>
  
  <p>The R code calling WinBUGS:</p>
  
  <pre><code># Prepare data
  ni = 12 #Nb of tagging year
  prL &lt;- c(0.13,0.23,0.28,0.22,0.29,0.25,0.31,0.32,0.32,0.40,0.33,0.35) #Proportion of tag lost
  input.tlr &lt;- list(ni=ni,prL=prL)
  
  # Generates intial values for two chains
  nbchains = 2
  init1 &lt;- list(beta1=runif(1,-1,1),beta2=runif(1,-1,1),tauG=rgamma(1,1,1))
  init2 &lt;- list(beta1=runif(1,-1,1),beta2=runif(1,-1,1),tauG=rgamma(1,1,1))
  inits &lt;- list(init1,init2)
  
  # Call WinBUGS
  parameters &lt;- c("gamma","beta1","beta2","tauG")
  out.tlr &lt;- bugs(data=input.tlr, inits=inits, parameters=parameters, "tlr.txt", n.chains=2, n.iter=20000, n.burnin=5000,n.thin=1,debug=TRUE)
  </code></pre>
  
  <p>The WinBUGS code is:</p>
  
  <pre><code>model {
  ###### Tag lost rate model ######
  for (i in 1:ni) {
    prL[i] ~ dnorm(gamma[i],tauG)
    gamma[i] &lt;- beta1 * log(i-0.5) + beta2
    }
  ### Priors
      beta1 ~ dnorm(0,0.001)
      beta2 ~ dnorm(0,0.001)
      tauG ~ dgamma(0.001,0.001)
  } # End model
  </code></pre>
  
  <p>And the WinBUGS output is: </p>
  
  <pre><code>display(log)
  check(C:/Users/AppData/Local/Temp/RtmpG8dxh1/tlr.txt)
  model is syntactically correct
  data(C:/Users/alebris/AppData/Local/Temp/RtmpG8dxh1/data.txt)
  data loaded
  compile(2)
  model compiled
  inits(1,C:/Users/AppData/Local/Temp/RtmpG8dxh1/inits1.txt)
  chain initialized but other chain(s) contain uninitialized variables
  inits(2,C:/Users/AppData/Local/Temp/RtmpG8dxh1/inits2.txt)
  model is initialized
  gen.inits()
  command #Bugs:gen.inits cannot be executed (is greyed out)
  thin.updater(1)
  update(5000)
  set(gamma)
  set(beta1)
  set(beta2)
  set(tauG)
  set(deviance)
  dic.set()
  update(15000)
