Can anyone tell me if there is a way to pass a value, say the session pid, to the global environment with a plumber API?
I have tried the <<-
operator, but doesn't work.
here's a really simple example :
(my_file.R)
#* @param x My argument
#* @get /lag_lead
function(x){
return(x*2)
api_pid <<- Sys.getpid()
}
and the script to run the api :
library(plumber)
mon_api <- plumb('my_file.R')
mon_api$run(port = 8000)
You are return
-ing before the assignment, i.e. it does not take effect. Try
#* @param x My argument
#* @get /lag_lead
function(x){
api_pid <<- Sys.getpid()
return(x*2)
}
