I am trying to create a simple text listing UI on the shiny dashboard. For this, I made an R function, which needs to store each text inputs to store in a list.
readtasks <- function() {
df <- list()
while(TRUE) {
tasks <- readline(prompt="type your tasks: ")
# stop reading if no text was typed in
if (tasks == '')
break
# add the read data to the bottom of the list
df <- append(df,tasks)
}
print(df)
}
The function works good for my needs, but when it comes to shiny it shows so many errors. I am eagerly want to know, how this while loop can efficiently implement to shiny. I search a lot in google and StackOverflow about this.if possible please give me an example.
Thank you
