Creating a data frame that is manually input from user

[RyanPhelps]

I would like to create a data frame that asks user for input and stores the variable in each specific cell. I've been looking it up, but cannot find specifically how to do it.

I don't think RStudio offers a user interface. You could build one with shiny and for example DT though. DT provides an editable table widget. Here's an example. You could then save df somewhere.

library(tidyverse)
library(shiny)
library(DT)
df <- tibble(a=rep("Empty",2), b=rep("Empty",2)) # initial dataframe
ui <- fluidPage(
	DTOutput("my_table")
)
server <- function(input,output,session){
	output$my_table <- renderDT({
		cat("render DT\n")
		DT::datatable(df,
					  options = list(lengthChange=FALSE, ordering=FALSE, searching=FALSE,
					  			   stateSave=TRUE, scrollX=FALSE, paging=FALSE, info=FALSE),
					  editable = TRUE
		)
	})
	observeEvent(input$my_table_cell_edit, {
		info <- input$my_table_cell_edit
		str(info)
		i = info$row
		j = info$col
		v = info$value
		cat("my_table edited", i, j, v, "\n")
		df[i,j] <- v
		print(df)
	})
}
shinyApp(ui, server)

How would i use this to where they input it in and it saves the value they input, but also allows for editing if inputted wrong
