shiny trying to install data.table and failing, even though I am not using the package

[BillPetti]

I am trying to deploy a shiny app but the build fails with the following error message:

Preparing to deploy application...DONE
Uploading bundle for application: 4367037...DONE

I am not using data.table in the app, so not sure why it's trying to install it at all. I do have a development version installed, which isn't on CRAN, but again I can't figure out why it's trying to install it in the first place:

library(dplyr)
library(tidyr)
library(purrr)
library(scales)
library(ggplot2)
library(DT)
library(shiny)
library(lme4)
library(merTools)

Great catch, I missed the recursive aspect and wasn’t seeing it as a dependency. I originally installed a dev version, but because I didn’t use devtools::install_github shiny was looking for the version on CRAN.

Reinstalled and now it’s deploying without a problem. Thanks!
