Problem running a Shiny app remotely about choroplethr HOT 11 CLOSED

Hi pssguy,

Sorry for the delay in replying to you. I just saw this post now. Let me first figure out how I can get emailed whenever there are issues created and then reply to your question.

OK, it looks like I just needed to "watch" this repo in order to get emails whenever new issues are created. The source of the confusion is that right before releasing the project we copied it from my personal repo to the official Trulia organization, and I didn't realize that I needed to explicitly watch this repo to get notified of new issues.

A few people have reported issues with 2.15 on the choroplethr google group: https://groups.google.com/forum/#!topic/choroplethr/Owv7NgAacGE

One user seems to have tracked down the specific issue to this:

http://comments.gmane.org/gmane.comp.lang.r.ggplot2/5743

I would like it if choroplethr worked seemlessly with shiny; this package seems like a natural fit for an interactive website. Do you have any information on why glimmer is not useing R version 3?

I think that the safest thing for me to do at this point is to place an explicit R version requirement as you suggested, and increase the release version of choroplethr to 1.0.1.

@pssguy I have a question about the shiny/glimmer deploy process. How are you handling setting the call to acs's api.key.install? I wonder if one of the issues is that this call has not been set on their remote server. For example, after playing with your app for a bit I get this error message:

Error: trying to get slot "estimate" from an object of a basic class ("logical") with no slots

To me this indicates that the call to get acs data failed.

@pssguy I just posted an issue about this on the shiny-discuss google group: https://groups.google.com/forum/#!topic/shiny-discuss/RWDtJMsor14

Hopefully we can get this to work. I think that the project you are trying to do would be pretty neat if we can get it to work.

@pssguy There are now two good suggestions listed in that forum. Please try them and report back whether they solve your problem.

@pssguy choroplethr version 1.1.0 was just accepted to CRAN. Please retry with that version and report back whether that solves your problem.

The Error: trying to get slot "estimate" from an object of a basic class ("logical") with no slots is a key issue
If I put my key in the acs.fetch function the error no longer occurs

I then get the "Non-finite location and/or size for viewport" error which is the R version issue

I tried installing version 1.1 on glimmer, but of course you have now set a dependency of R>3.0.0 so it did not load as glimmer runs on an earlier version. This had the unfortunate side effect of removing the version 1.0 which was on the glimmer server. So the app will not work at all on glimmer for me now and I am not able to test whether adding the 'maps' package would have helped. Not sure there is any way round this without you setting up a new version removing the dependency and I could reinstall via github? Of course it currently runs without error on mytinyshinys.com/acs, although I have yet to update to v1.1 there and it is not yet a finished product. Anyone wishing to use the package and run on glimmer may of course, still encounter difficulties

The link I sent you

https://groups.google.com/forum/#!topic/shiny-discuss/RWDtJMsor14

mentions people using other alternatives to glimmer: shinyapps.io and spark. Have you tried those?

I'm not familiar with the shiny package enough to help further. Winston Chang is listed as the package maintainer for Shiny (see http://cran.r-project.org/web/packages/shiny/index.html). I recommend emailing him asking for further guidance. Feel free to cc me on the email.

I think spark is just another server using R 2.15 shinyapps.io is only in alpha as far as I know. For both of those you have to set up an account like I have on glimmer. If you have an archive of v 1.0 which does not depend on R 3 I suppose could try an install that on glimmer but, to be honest, as v 1.1 works locally and I presume on my other site and has extra features I'm not that bothered now

from choroplethr.

Regarding an archive: since this project uses git and github, there is an archive of everything :)

Your best bet is probably to fork the repo and make whatever changes you like to that new repo. These changes can include reverting to a previous release tag. If you are not sure how to do this, then a good place to start might be github's training: http://training.github.com/.

I just discovered a problem with 1.1.0 which I describe here: https://groups.google.com/forum/#!topic/rdevtools/me-cJWRmQo0. So I am currently working on a patch for version 1.1. But I am not sure if this will help with your problem.

Hi,

I am at the R User Conference now and asked a question about this to the developers of shiny. Glimmer is now deprecated. The new version is https://www.shinyapps.io/, and it should have the latest version of R installed.
