I wanted to test renv package for shiny app.
here is my dummy app :
library(pool)
library(fresh)
library(shiny)
ui <- fluidPage(
titlePanel("Old Faithful Geyser Data"),
sidebarLayout(
sidebarPanel(
sliderInput("bins",
"Number of bins:",
min = 1,
max = 50,
value = 30)
),
mainPanel(
plotOutput("distPlot")
)
)
)
server <- function(input, output) {
output$distPlot <- renderPlot({
x <- faithful[, 2]
bins <- seq(min(x), max(x), length.out = input$bins + 1)
hist(x, breaks = bins, col = 'darkgray', border = 'white')
})
}
shinyApp(ui = ui, server = server)
Note that I just load 2 libraries pool and fresh without using them.
init() command from renv package is creating a local library on my project path :
renv::init("/home/z0044uca/mytest_renv/")

The following package(s) will be updated in the lockfile:

Restarting R session...
* Project '~/mytest_renv' loaded. [renv 0.12.5]
My question is how could I deploy the app to my shiny- server without installing the two packages (pool and fresh) on the server.
When I copied the entire folder (mytest_renv) to my server and tried to run the app in browser, I got the following error (in the log file )
Warning message:
The following package(s) are missing entries in the cache:
base64enc, BH, commonmark, crayon, DBI, digest, fastmap,
fresh, fs, glue, htmltools, httpuv, jsonlite, later,
magrittr, mime, pool, promises, R6, rappdirs, Rcpp, rlang,
rstudioapi, sass, shiny, sourcetools, withr, xtable
These packages will need to be reinstalled.
Error in loadNamespace(name) : there is no package called ‘digest’
Calls: local ... loadNamespace -> withRestarts -> withOneRestart -> doWithOneRestart
Execution halted
I was expecting that the renv folder inside my app directory take care of all the packages and dependencies.
