[英]multiple conditions observeEvent - R Shiny
I am trying to do a Shiny app with an interactive map displaying marine animal tags.我正在尝试制作一个 Shiny 应用程序,其中包含一个显示海洋动物标签的交互式 map。 Currently, I have three possible inputs: (1) The tag numbers, (2) the size of the animals and (3) the month I want to display.
目前,我有三个可能的输入:(1) 标签编号,(2) 动物的大小和 (3) 我想要显示的月份。 For the size it works easily as I update the tag number input, but I am stuck with the months... I already tried with:
对于它的大小,当我更新标签号输入时它很容易工作,但我坚持了几个月......我已经尝试过:
observeEvent({input$selected_tag
input$selected_month},{...
and by including the inputs inside a reactive expression but an error occur:并通过将输入包含在反应式表达式中但会发生错误:
Avis : Error in sum: 'type' (list) de l'argument incorrect
Would you have an idea please?请问你有什么想法吗? Or are my inputs poorly defined (cf the error)?
还是我的输入定义不明确(参见错误)? Here is a reprex and a sample of my data https://github.com/rc.net/ABFT_migration/blob/main/test_file.csv (line with #### What happens when you click on a tag? ####):
这是一个代表和我的数据样本https://github.com/rc.net/ABFT_migration/blob/main/test_file.csv (符合 #### 当你点击标签时会发生什么?### #):
library(shiny)
library(leaflet)
library(lubridate)
#### Data loading ####
### Tags table
tag_data <- read.csv("test_file.csv", header = TRUE, sep=",",dec=".")
tag_data$tag <- as.factor(tag_data$tag)
id_tag <- levels(tag_data$tag)
tag_data$date = ymd(tag_data$date)
## Definition of the applicable filters
filtering_option <- c("Size", "Months")
## Definition of the seasons
months_tag <- c("January", "February", "March", "April",
"May", "June", "July", "August", "September",
"October", "November", "December")

#### Shiny app UI ####
ui <- fluidPage(
tabsetPanel(
column(2, selectizeInput("selected_tag", "Which tags do you want to see ?",
choices = id_tag, multiple = TRUE),
hr(), ## Filters
p(strong("Which filter do you want to use ?")),
checkboxInput("filter_size", "Size"),
conditionalPanel(condition = "input.filter_size == 1",
sliderInput("slider_size", "Choose a size range (in cm)",
value = c(min(unique(tag_data$size_at_tagging)),
max(unique(tag_data$size_at_tagging))),
min = min(unique(tag_data$size_at_tagging)),
max = max(unique(tag_data$size_at_tagging)))
),
checkboxInput("filter_month", "Months"),
conditionalPanel(condition = "input.filter_month == 1",
selectizeInput("selected_month",
"Which months do you want to see ?",
choices = months_tag,
selected = months_tag[1],
multiple = TRUE)),
actionButton("reset_button", "Reset"),

column(10, leafletOutput("map_tag", height = "850px"))
))

#### Shiny app server ####
server <- function(input, output, session) {
observeEvent(input$selected_month, {cat(input$selected_month, "\n")})
observeEvent(input$selected_tag, {cat(input$selected_tag)})
}
shinyApp(ui, server)
''' '''
you can define a list of desired input parameters:您可以定义所需输入参数的列表:
toListen <- reactive({
list(input$selected_tag, input$selected_month)
})
and then use your reactive list in combination with your observeEvent
:然后将您的反应列表与您的
observeEvent
结合使用:
observeEvent(toListen(),{...})
So after a few tries, I finally figure it out.所以经过几次尝试,我终于弄明白了。 The bug indeed was in the leaflet. The problem lied in the label argument of addAwesomeMarkers.
该错误确实在 leaflet 中。问题在于 addAwesomeMarkers 的 label 参数。 Change "label" by "popout" and it should be okay !
通过“弹出”更改“标签”,应该没问题! (As I had to reduce my reprex the error is no longer in my initial post)
(因为我不得不减少我的代表,错误不再出现在我最初的帖子中)
