我正在编写一个Shiny应用程序来创建一个包含数据集中每个变量的表的行。变量的数量将从使用变为使用,理想情况下,应用程序将输出与变量一样多的行和表。我当前的代码是创建正确的行数和文本数,但是重复所有行的最后一个表的表数据。我认为在output[[tablename]]
中存储表输出可能不适合创建单独存储的表。下一步是添加一个反应性输入来过滤vardata$category
显示的行。
这里的代码包括数据示例:
library(shiny)
variable <- c("Q17r01", "Q17r01", "Q17r01", "Q22r03", "Q22r03", "Q22r03", "Q15r01", "Q15r01", "Q15r01", "S03", "S03", "vAge", "vAge", "vAge", "vAge", "vAge", "vAge")
responses <- c("A_T", "B_M", "C_B", "A_T", "B_M", "C_B", "A_T", "B_M", "C_B", "Female", "Male", "13 - 17", "18 - 24", "25 - 34", "35 - 44", "45 - 54", "55+")
grp1 <- c(33, 39, 28, 27, 20, 53, 88, 7, 5, 51, 49, 27, 8, 33, 14, 16, 2)
grp2 <- c(42, 46, 12,41, 45, 13, 64, 32, 4, 44, 56, 9, 22, 39, 13, 12, 4)
xAgg <- c(32, 49, 19, 26, 48, 26, 51, 38, 11, 45, 55, 12, 16, 30, 17, 14, 11)
chartdata <- data.frame(variable,responses,grp1,grp2,xAgg,row.names=NULL)
profvars <- unique(variable)
varlabel <- c("Q17r01_I_am_overwhelmed_by_the_number_of_apps_available_for_download", "Q22r03_I_feel_overwhelmed_by_the_number_of_digital_communications_I_receive",
"Q15r01_When_I_receive_a_message_online_I_tend_to_respond_right_away", "S03_Please_indicate_your_gender", "vAge_Age_breakdown")
category <- c("a_Causes_of_Stress", "a_Causes_of_Stress", "a_Communication_Availability", "zz_Demo", "zz_Demo")
vardata <- data.frame(profvars,varlabel,category,row.names=NULL)
chartdatasplit <- split(chartdata, chartdata$variable)
server <- function(input, output) {
assigntables <- reactive({
for (vars in profvars){
local({
var <- vars
tablename <- paste0("table.",var)
assign("tabledata",chartdatasplit[[var]],pos=1)
output[[tablename]] <- renderTable({tabledata}) ###appears this is only being done for last table
})
}
})
output$AllVars <- renderUI({
##for (i_var in 1:nrow(vardata)) {
assigntables()
return(apply(vardata,1,function(vars){
fluidRow(column(12,offset=1,
tableOutput(paste("table.",vars['profvars'],sep=''))),
hr()
)
}))
})
}
ui <- navbarPage("Seg Run",
tabPanel("Summary",
uiOutput("AllVars")
)
)
shinyApp(ui = ui, server = server)
答案 0 :(得分:2)
我们走了:
