我已經成功地放入了一年的滑塊並創建了一個ggplot。但是,我很難弄清楚如何按年來過濾數據(目前它每年都會顯示一次),如滑塊所示。R Shiny:每年將ggplot鏈接到滑動條
如何獲取數據:
library(WDI)
xdat <- WDI(indicator=c('NY.GNP.PCAP.CD', 'SH.DYN.MORT', 'SP.POP.TOTL', 'SP.DYN.LE00.IN', 'SP.DYN.TFRT.IN'), start=1960, end=2014, extra=TRUE)
sdata <- subset(xdat, xdata$region != "Aggregates")
sdata <- na.omit(sdata)
sdata$reg <- ifelse(sdata$region == "Europe & Central Asia (all income levels)", 1, ifelse(sdata$region == "Middle East & North Africa (all income levels)", 2, ifelse(sdata$region == "South Asia", 3, ifelse(sdata$region=="Latin America & Caribbean (all income levels)", 4, ifelse(sdata$region=="Sub-Saharan Africa (all income levels)", 5, ifelse(sdata$region=="East Asia & Pacific (all income levels)", 6, ifelse(sdata$region=="North America", 7, 0)))))))
sdata$col <- ifelse(sdata$reg == 1, "#FFFFFF", ifelse(sdata$reg == 2, "yellow", ifelse(sdata$reg == 3, "red", ifelse(sdata$reg== 4, "green", ifelse(sdata$reg== 5, "orange", ifelse(sdata$reg==6, "lavender", ifelse(sdata$reg== 7, "pink", 0)))))))
ui.r
library(googleCharts)
shinyUI(fluidPage(
plotOutput("view"),
titlePanel("title panel"),
column(
sliderInput("slider1", label=h3("Slider"),
min=1960, max=2014, value=50, sep="", animate=TRUE),
),
fluidRow(
column(
radioButtons("radio", label=h3("Radio buttons"),
choices = list("Mortality" = 1, "Choice 2" = 2, "Choice 3" = 3), selected=1)),
sidebarLayout(
sidebarPanel(""),
mainPanel("Main")
))
))
server.r
library(dplyr)
shinyServer(function(input, output) {
output$view <- renderPlot({
ggplot(sdata, aes(x=NY.GNP.PCAP.CD, y = SP.DYN.LE00.IN)) + geom_point(aes(size=pop^(0.75)/20000000+2, colour=col))
})
})
的問題是,每年都顯示出來,當我使用滑塊,它什麼都不做:
我也想知道如何使用單選按鈕來更改變量。
不幸的是沒有工作。 –
現在應該工作,我看到你只是改變了開始輸入,所以'輸入$ slider1'現在選擇最小年份 – timfaber
也許這是我的ui.r? –
