Hi ElMaestro,

❝ You can try the following simpler example:

a=system(command="hamburger", intern=T)

❝ The following is printed to the console:

sh: 1: hamburger: not found

❝ Error in system(command = "hamburger", intern = T) :

❝ error in running command

❝ But this isn't the content of the variable a as I was hoping. Note that in this example, an error is produced but not in the R sense, only in the system (or system2) sense. Thus, there is no gain in putting the code into try{} brackets.


maybe I misunderstood your goal but won't
tryCatch(
  {   
    a <- system(command="hamburger", intern = T)
  }, 
  error = function(cond) {
    a <<- cond
  }
)

work?

Kind regards,
Mittyri

You can do one of two things; just shut up,
which is something I don’t find easy,
or learn an awful lot very fast,
which is what I tried to do.    Jane Fonda
