ui <- fluidPage(

theme = shinytheme("flatly"),
tags$h1("Determinants", style = "font-weight: bold; text-align; center;"), sidebarPanel( selectInput("matrix", "Choose a matrix dimension:"), c("2x2", "3x3"), submitButton("trigger", "Set as Matrix") ), ) ) ), tabPanel("About", sidebarPanel( h2("About the App", style = "font-weight: bold;"), ) )
I am trying to figure out how to insert a "Selection Option" for my Matrix Calculator as I stumbled upon an error, it says that "Error in choicesWithNames(choices) :
argument "choices" is missing, with no default"
I wish to create a selectioninput, whereas to limit my matrix to 2x2 and 3x3. However, I still cannot figure out how I can move from the next progress as I am stucked with this error since yesterday. I also wish to know for a possible insight to my project as I am learning R/shinyapp. My app is a Determinant Calculator.
