Small Progress Tonight


   I am typing this from my laptop at home. The good news is that my control chart can udpate based on the contract order number. I still have yet to update it based on the variables, but it is still progress nonetheless. Now, I am trying to subset the data set by column. I was able to do it by row, so now I need to do it by column.

library(qcc)
library(shiny)
library(DT)



mydata <-read.csv("dummydata.csv")
variables <- 1:ncol(mydata)
names(variables) <- names(mydata)
equipment <- mydata[1:nrow(mydata), c("CON")]



ui <- fluidPage(
  titlePanel("Control Charts"),
  sidebarLayout(
    sidebarPanel(
      fileInput("file1", "Choose a file in CSV format", accept = c("text/csv", "text/comma-separated-values,text/plain",
                                                                   ".csv")
      ), #fileInput
   
      hr(),
   
      selectInput(inputId = "equip", label = "Contract Order Number:", choices = equipment), #selectInput
   
   
      selectInput(inputId = "var", label = "Choose which variable you want to graph", choices = variables), #selectInput
