I am wondering if there is a way to pass a reactive value, for example the result of shiny::numericInput() , as a parameter to python code in a python chunk. sample code below:
---
title: "rective R value in python code reprex"
output: html_document
---
```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = FALSE)
library(reticulate)
library(tidyverse)
library(shiny)
```
## non-reactive input
```{r}
my_number <- 4
```
(note: the chunk below is a python chunk defined using `{python}` in the chunk header)
```{python}
def my_function(x):
return 5 * x
result = my_function(int(r.my_number))
```
works when kitting!
```{r}
py$result
```
----------
## trying with reactive input
```{r}
shiny::numericInput(inputId = "number_select", label = "Number", value = 4, min = 1, step = 1)
my_number <-
reactive(input$number_select)
```
(note: the chunk below is a python chunk defined using `{python}` in the chunk header)
```{python}
def my_function(x):
return 5 * x
# the following line results in error:
# Error in py_call_impl(callable, dots$args, dots$keywords) :
# RuntimeError: Evaluation error: Operation not allowed without an active reactive context.
# * You tried to do something that can only be done from inside a reactive consumer..
result_reactive = my_function(int(r.my_number()))
# removing the parens results in error:
# Quitting from lines 43-54 (reprex_example.Rmd)
# Error in py_call_impl(callable, dots$args, dots$keywords) :
# TypeError: int() argument must be a string, a bytes-like object or a number, not 'function'
result_reactive = my_function(int(r.my_number))
```
never makes it to this step whe knitting :(
```{r}
py$result_reactive
```
