How to include arguments in Foo_Bot?

Hello, it is not clear to me how to include the arguments of the functions in Foo_Bot to later call them from Telegram. For example, the following doesn't work:

sum_fun <- function(x, y){return(x+y)}

Function_List$Foo4 <-
  list(Function = sum_fun,
       Call = "Sum_Example",
       Args = TRUE,
       Message = "x and y")

Foo_Bot(Bot_Name = Bot_Name, Function_List = Function_List, LoadMessage = "My connection with R",
        KillR = TRUE, KillCPU = FALSE)

If I make the following call from Telegram I get the following error:

/Sum_Example c(x = 1, y = 3)

Function ERROR (Connection still open): Function: /Sum_Example

Error details: Error in .f(...): argument "y" is missing, with no default

I constantly come across this error and I don't understand how to enter the arguments of the functions... could you shed some light on it?

Thanks.

Hi Alberto,

First, you can replicate the error you are receiving in R by running:

  sum_fun <- function(x,y){print(x, y)}
  args <- c(1,2)
  sum_fun(args)

The idea with Foo_Bot is really to kick off more advanced processes on user side, as opposed to allowing multiple argument inputs from Telegram.

Foo_Bot it takes in a vector argument - so to achieve what you wanted, you could rather try:

sum_fun1 <- function(x){ print(sum( as.numeric(x) ) ) }

Function_List$Foo1 <- list(Function = sum_fun1, Call = "SE", Args = TRUE, Message = "x and y")

Foo_Bot(Bot_Name = "YourBot", Function_List = Function_List, LoadMessage = "My connection with R", KillR = TRUE, KillCPU = FALSE)

And in Telegram run:

/sum_fun1 1 2 3 4 5

Which should give you sum(1,2,3,4,5) in the prompt in R.

From a worfklow perspective- rather have many function calls ready (with appropriate names) that you can call that can execute more advanced commands on your side, as opposed to allowing multiple inputs to functions (like your sum example).

This means you should try to plan a workflow that requires single vector inputs ideally (as my example shows).

As an example, I've built calls in the past that execute functions on my side such as:

Exe_Foo <- function(X){ source( "XXXX/Function_myside_to_Source.R" )) Function_myside(X) }

And then from telegram:

/ Exe_Foo SP500

/Exe_Foo Nikkei

Which will then kick off processes.

Hope this helps?
