Important: Read this before posting to this forum

  1. This forum is for questions related to the use of Apollo. We will answer some general choice modelling questions too, where appropriate, and time permitting. We cannot answer questions about how to estimate choice models with other software packages.
  2. There is a very detailed manual for Apollo available at http://www.ApolloChoiceModelling.com/manual.html. This contains detailed descriptions of the various Apollo functions, and numerous examples are available at http://www.ApolloChoiceModelling.com/examples.html. In addition, help files are available for all functions, using e.g. ?apollo_mnl
  3. Before asking a question on the forum, users are kindly requested to follow these steps:
    1. Check that the same issue has not already been addressed in the forum - there is a search tool.
    2. Ensure that the correct syntax has been used. For any function, detailed instructions are available directly in Apollo, e.g. by using ?apollo_mnl for apollo_mnl
    3. Check the frequently asked questions section on the Apollo website, which discusses some common issues/failures. Please see http://www.apollochoicemodelling.com/faq.html
    4. Make sure that R is using the latest official release of Apollo.
  4. If the above steps do not resolve the issue, then users should follow these steps when posting a question:
    1. provide full details on the issue, including the entire code and output, including any error messages
    2. posts will not immediately appear on the forum, but will be checked by a moderator first. This may take a day or two at busy times. There is no need to submit the post multiple times.

Error with apollo_prediction

Post by richardqiu »

Dear Prof Hess,
I am using Apollo v0.2.6 and working on the prediction of a LC model. I've received the following error message when using the apollo_prediction function.

Code: Select all

Error in if (is.matrix(P[[j]][[k]]) & ncol(P[[j]][[k]]) == nInter) P[[j]][[k]] = rowMeans(P[[j]][[k]]) : 
  argument is of length zero
I traced the error back to the apollo_avgInterDraws function and noticed that in line 106, the code is running as

Code: Select all

if (is.matrix(P[[j]][[k]]) & ncol(P[[j]][[k]]) == 
                nInter)
It seems to me that the condition should be && instead of &, as the second condition should not be evaluated if the first condition is FALSE.
Could you please take a look?

Thank you!

Richard
