Overview and tree view empty in shinyMixR interface.

[sg033]

Hi, I'm trying to teach myself nlmixr and also how to use shinyMixR.

When I create a new project and then run shinymixr in a browser (run_shinymixr(launch.browser=TRUE)) , the interface appears but is empty. I am running it on windows and have shiny, nlmixr, and shinymixr installed. It's most likely that I have done something incorrectly but can't figure out what.

Any help would be greatly appreciated. Thanks.

I am not entirely sure but I suspect it has something to do with the working directory. I would make sure that the working directory is the location where your project (models) are located. You can check with getwd() if this is correct. As a first test you can create a start project in your current working directory using create_proj(). Then you can try to start the interface using run_shinymixr(launch.browser = TRUE). If this doesn't work could you please provide some additional information (e.g. output from sys.Info() and warnings/errors issued by R)?

My project is in"C:/ProjectFolder". When I check with getwd() it confirms this:

getwd() [1] "C:/ProjectFolder" Also, when I also create a new project in the working directory as you said and start the interface, it is still empty.

The only warning messages I get are: 1: package ‘shiny’ was built under R version 3.6.3 2: package ‘nlmixr’ was built under R version 3.6.3

Sys.info sysname: "Windows" release: "10 x64" version "build 15063" machine "x86-64"

If you need any further information, just let me know. Thanks so much.

I did some additional testing and initially had similar issues. After updating packages everything worked as expected. I would at least install the latest development version of shinyMixR devtools::install_github("richardhooijmaijers/shinyMixR"). This will also ask to install/update all related packages. If you have done this and still encounter issues could you provide the output from sessionInfo() ? This will give me a chance to look at all the package versions and try to reproduce the behavior.

I tried to update the version of shinyMixR in R 3.6.1 that came with the windows installer for nlmixr but it didn't work, I got the error:

Failed to install 'shinyMixR' from GitHub:

(converted from warning) installation of package ‘C:/Users/AppData/Local/Temp/Rtmp8Ipr6l/file4dec1884734/shinyMixR_0.2.0.tar.gz’ had non-zero exit status

So then I decided to download R 4.0 and then installed all of the programmes again, including shinymixr, and it worked! Wonderful. Thank you so much for all your help.

Great to hear that it worked out in the end, glad I could help! Also thanks for providing the additional error considering the installer, we will have a look at it and make sure it works in the upcoming version.
