[英]Filter data frame using checkboxGroupInput
I want to create a scatterplot using R-Shiny App. 我想使用R-Shiny App创建一个散点图。 I need 2 input (selectInput and checkboxGroupInput) to display my plot.
我需要2个输入(selectInput和checkboxGroupInput)来显示我的绘图。 When I run the code, it show this error :
当我运行代码时,它显示此错误:
Error: (converted from warning) Error in : (converted from warning) Error in max: (converted from warning) no non-missing arguments to max;
错误:(从警告转换)错误:(从警告转换)最大错误:(从警告转换)没有不可缺少的参数传递给max; returning -Inf
返回-Inf
It seems that selectInput is OK but not checkboxGroupInput, because when I try to filter data with 2 selectInput, it works... See my code : 似乎selectInput可以,但checkboxGroupInput不能,因为当我尝试使用2 selectInput过滤数据时,它可以工作...请参阅我的代码:
ui = fluidPage(
headerPanel('Title'),
sidebarPanel(
selectInput(inputId = 'adv', label = 'Adversaire', choices = levels(nodes$Adversaire)),
checkboxGroupInput(inputId = 'act', label = 'Actions', choices = levels(nodes$Action))
),
mainPanel(plotOutput('scatter'))
)
server <- function(input, output) {
data = reactive({
df = nodes %>%
filter(Adversaire == input$adv, Action %in% c(input$act)) %>%
group_by(Player) %>%
summarise(Poste = unique(Poste),
Pour_brut = sum(Pour), Contre_brut = sum(Contre), Total_brut = sum(Total),
Pour = sum(Pour_brut)/mean(unique(Time))*20, Contre = sum(Contre_brut)/mean(unique(Time))*20, Total = sum(Total)/mean(unique(Time))*20,
Time = mean(unique(Time)))
})
output$scatter = renderPlot({
ggplot(data(), aes(x = Contre, y = Pour, color = Poste, size = Time)) +
scale_x_continuous(limits = c(0,max(c(data()$Contre, data()$Pour)))) +
scale_y_continuous(limits = c(0,max(c(data()$Contre, data()$Pour)))) +
geom_abline(intercept = 0, slope=1) +
geom_point()
})
}
shinyApp(ui = ui, server = server)
EDIT : 编辑:
structure(list(Player = c(14L, 12L, 96L, 25L, 19L, 96L), Poste = structure(c(2L,
1L, 1L, 2L, 1L, 1L), .Label = c("Attaquant", "Defenseur"), class = "factor"),
Match = c(2L, 2L, 2L, 2L, 2L, 2L), Adversaire = structure(c(2L,
2L, 2L, 2L, 2L, 2L), .Label = c("Amiens", "Nice"), class = "factor"),
Action = structure(c(3L, 3L, 3L, 2L, 2L, 2L), .Label = c("But",
"FO", "JOZO", "PK 4vs5", "PP 5vs3", "PP 5vs4", "SZC", "SZSPR",
"TOZD", "TOZN", "TOZO"), class = "factor"), Pour = c(2L,
2L, 2L, 2L, 1L, 1L), Contre = c(1L, 2L, 1L, 0L, 0L, 0L),
Total = c(3L, 4L, 3L, 2L, 1L, 1L), Time = c(12.89, 11.33,
11.11, 14.42, 10.12, 11.11)), row.names = c(NA, 6L), class = "data.frame")
This worked fine for me. 这对我来说很好。 Just make sure
Adversaire
and Action
are character fields. 只要确保
Adversaire
和Action
是字符字段即可。 Also added req(nrow(data()) > 0)
to renderPlot()
to get rid of max
function warnings - req(nrow(data()) > 0)
到renderPlot()
以摆脱max
功能警告-
ui = fluidPage(
headerPanel('Title'),
sidebarPanel(
selectInput(inputId = 'adv', label = 'Adversaire', choices = unique(nodes$Adversaire)),
checkboxGroupInput(inputId = 'act', label = 'Actions', choices = unique(nodes$Action))
),
mainPanel(plotOutput('scatter'))
)
server <- function(input, output) {
data <- reactive({
df <- nodes %>%
filter(Adversaire == input$adv, Action %in% input$act) %>%
group_by(Player) %>%
summarise(
Poste = unique(Poste),
Pour_brut = sum(Pour), Contre_brut = sum(Contre),
Total_brut = sum(Total),
Pour = sum(Pour_brut)/mean(unique(Time))*20,
Contre = sum(Contre_brut)/mean(unique(Time))*20,
Total = sum(Total)/mean(unique(Time))*20,
Time = mean(unique(Time))
)
df
})
output$scatter = renderPlot({
req(nrow(data()) > 0)
ggplot(data(), aes(x = Contre, y = Pour, color = Poste, size = Time)) +
scale_x_continuous(limits = c(0,max(c(data()$Contre, data()$Pour)))) +
scale_y_continuous(limits = c(0,max(c(data()$Contre, data()$Pour)))) +
geom_abline(intercept = 0, slope=1) +
geom_point()
})
}
