Error in library(dplyr) : there is no package called ‘dplyr’

[Bodong Chen]

Hi,

I was trying to deploy an app to Shinyapps.io.  The deployment went through but the webpage failed to load because of an issue related to dplyr (see below).  I searched posts in this group, re-installed dplyr locally, and made sure library(dplyr) was called in my code. However, this issue is still there. It would be greatly appreciated if you could give me some tips. Thank you.

Below is the error log:

Are you publishing from using the IDE button or are you using the shinyapps package?

Can you send over the output from:

rsconnect::appDependencies('path/to/your/app')

Hi Andy,

I tried both, which returned the same results. When deploying using the package, I ran the following:

> library(shinyapps)

> rsconnect::deployApp()

Below are the results of appDependencies. No appearance of dplyr, so are other packages like googlesheets. Wondering whether I did anything wrong. Any tips will be appreciated.

> rsconnect::appDependencies()

     package version source

1         R6   2.1.1   CRAN

2       Rcpp  0.12.1   CRAN

3     digest   0.6.8   CRAN

5     httpuv   1.3.3   CRAN

Do you use packrat to manage package dependencies? 

Can you try removing the packrat directory from your application folder and re-running appDependencies()?

I was not using Packrat and double-checked in RStudio that the project is not using Packrat. Any other thoughts?

[Andy Kipp]

Did you try deleting that directory?

[Andy Kipp]

Also what version of packrat do you have? Can you make sure its the latest and you've restarted R?

[Bodong Chen]

I guess I don't understand what you meant by "deleting that directory". Sorry I am not familiar with Packrat at all. There is no related directory under the project. I did try to remove the rsconnect folder. 

> packrat::snapshot()

Error: This project has not yet been packified.

Run 'packrat::init()' to init packrat.

I also updated Packrat and restarted R. Same results.  Thanks much for helping out.

I upgraded R and the issue went away!! Thanks a lot for your help.
