r - Fixing the order of facets in ggplot -


data:

type    size    amount   t   50%     48.4     f   50%     48.1     p   50%     46.8     t   100%    25.9     f   100%    26.0     p   100%    24.9     t   150%    21.1     f   150%    21.4     p   150%    20.1     t   200%    20.8     f   200%    21.5     p   200%    16.5

i need plot bargraph of above data using ggplot (x-axis -> "type", y-axis -> "amount", group "size"). when used following code, not getting variable "type" , "size" in order shown in data. please see figure. have used following code that. 

 ggplot(temp, aes(type, amount , fill=type, group=type, shape=type, facets=size)) + geom_bar(width=0.5, position = position_dodge(width=0.6)) + facet_grid(.~size) + theme_bw() + scale_fill_manual(values = c("darkblue","steelblue1","steelblue4"), labels = c("t", "f", "p"))

enter image description here .

for fixing order issue, have used factor method variable "type" using following. please see figure also.

temp$new = factor(temp$type, levels=c("t","f","p"), labels=c("t","f","p"))

enter image description here

however, don't know how fix order variable "size". should 50%, 100%. 150%, , 200%.

make size factor in dataframe by:

temp$size_f = factor(temp$size, levels=c('50%','100%','150%','200%'))

then change facet_grid(.~size) facet_grid(.~size_f)

then plot: enter image description here

the graphs in correct order.

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 ...
