"There is no package called X" error

[Eglantine Schmitt]

Hi everybody,

I have browsed this group and other forums looking for a solution but did no find any.

I a getting a "there is no package called arules" error message (in French) when opening the app. See: https://eglantine.shinyapps.io/RTextAnalytics/ 

My Shiny app works on my computer(s) and is successfully deployed to shinyapps.io using rsconnect::deployApp()

The deployment USED to work several months ago. Might have been using the shinyapps library instead of rsconnect, and obviously there were some updates to R and some of the packages I use in the app.

I have updated rsconnect today using devtools::install_github('rstudio/rsconnect')

Both my ui.R and server.R begin with:

library(shiny)

library(arules)

library(arulesViz)

library(jsonlite)

library(plyr)

library(igraph)

library(httr)

Both those files are in UTF-8 (without BOM).

Here is my sessionInfo()

[15] RCurl_1.95-4.8   rsconnect_0.8.3  memoise_1.0.0   

And my rsconnect::appDependencies()

       package version source
1           R6   2.2.0   CRAN
2         Rcpp  0.12.9   CRAN
3       digest  0.6.12   CRAN
4    htmltools   0.3.5   CRAN
5       httpuv   1.3.3   CRAN
6     jsonlite     1.3   CRAN
7         mime     0.5   CRAN
8      packrat 0.4.8-1   CRAN
9        shiny   1.0.0   CRAN
10 sourcetools   0.1.5   CRAN
11      xtable   1.8-2   CRAN

As you can see, the library "arules" is missing in appDdependencies.

I am not copying the app code because it is several hundreds lines long but I can if you think this might help.

I have no idea how to solve this.

Thanks in advance for any leads,

Eglantine

PS : sorry for the erratic formatting, Google group interface doesn't seem to like me.

How were the arules and arulesViz packages installed?

Are they available from CRAN? Could you try uninstalling and reinstalling them?

They are on CRAN et installed through install.packages()

I just tried uninstalling  (using remove.packages()) et reinstalling them.  I also cleared all objects from my workspace. My sessionInfo() looks a little different now.

Before running the app on my computer:
