R - source()'ing files in Shiny UI Layer -


i'm trying take shiny apps , break them smaller files make collaborating via git coworkers easier. this question helped me figure out how source() in files server.r using source(...,local=t). i'm trying same thing ui layer.

consider toy shiny app:

library(shiny)  ui <- bootstrappage(   plotoutput("test"),   numericinput("n","number of points",value=100,min=1) )  server <- function(input, output, session) {   output$test = renderplot({     x = rnorm(input$n)     y = rnorm(input$n)     plot(y~x)   }) }  shinyapp(ui, server)

this app expect, 1 overly-wide graph of 100 random data points. now, if want move plotoutput separate file (the real use case in moving whole tabs of ui separate files). make new file called tmp.r , has:

column(12,plotoutput("test"),numericinput("n","number of points",value=100,min=1))

the reason wrapping in column statement because comma's can't hanging out. update ui to:

library(shiny)  ui <- bootstrappage(   source("tmp.r",local=t) )  server <- function(input, output, session) {   output$test = renderplot({     x = rnorm(input$n)     y = rnorm(input$n)     plot(y~x)   }) }  shinyapp(ui, server)

now, word "true" hanging out @ bottom of page.snippet example of problem

how eliminate word showing up? why there?

try source("tmp.r",local = true)$value maybe

r - Update two sets of radiobuttons reactively - shiny -

i have read ( how make choices in radiobuttons reactive in shiny? ) shows me how update radiobutton s in reactive way. however, when try , update 2 sets of buttons same data, 1 set renders. example: server: # create example data wafer <- rep(c(1:3), each=3) length <- c(1,1,2,1,1,1,3,5,1) width <- c(3,1,6,1,1,1,1,1,6) dd <- data.frame(wafer, length, width) shinyserver(function(input, output, session){ # create reactive dataframe store data values <- reactivevalues() values$df <- data.frame() # lengths , widths of wafer user input <- eventreactive(input$do, { subset(dd, wafer %in% input$wafer, select = length:width) }) # update reactive data frame lengths , widths have been selected user input observe({ if(!is.null(a())) { values$df <- rbind(isolate(values$df), a()) } }) output$wl <- renderdatatable({ a() }) # update radio buttons unique length , widths stored in values$df # ever "observe" put first in co...

ios - Realm over CoreData should I use NSFetchedResultController or a Dictionary? -

i'm working on app using core data , nsfetchedresultcontroller many reasons switch use realm. saw there "realm version" of nsfetchedresultcontroller on github wouldn't compatible current code using core data. the view controller displaying list of people same school, address book. list sublist of people studied in same city. so thinking make 1 unique request database retrieve list of people , filter locally list within 1 dictionary per school [string: anyobject] string section name within tableview , anyobject array of people. first solution, make nsfetchedresultcontroller each school predicate filtering location. delete actions etc.. handled delegates -> not compatible realm create dictionaries , update them each actions... -> works realm it's annoying code. any better solution? edit: i need clarify request: i'd write class inherit uitableviewcontroller. this class has list of people sorted in alphabetical order the tableview has ...
