问题
i need to display interactive association rules plot in shiny. For that i am using arulesViz package. But when i am trying to display interactive scatter plot using the below:
shinyServer(function(input, output) {
output$plot1<-renderPlot({
rules <- apriori(transaction_all[[as.numeric(input$level)]],parameter=list(support=input$support,confidence=input$confidence))
plot(rules, measure=c("support", "lift"), shading="confidence",interactive = TRUE)
})
Its throwing an error:
Error in convertUnit(x, unitTo, "x", "location", "x", "location", valueOnly = valueOnly) :
'x' argument must be a unit object
How could this be done? Thanks
ui.R looks like this
shinyUI(pageWithSidebar(
# Application title
headerPanel("Sliders"),
# Sidebar with sliders that demonstrate various available options
sidebarPanel(
# Simple integer interval
selectInput("level", label = h3("select level to mine"),
choices = list("Level-1" = 1, "Level-2" = 2, "Level-3" = 3,"Level-4" = 4),
selected = 1),
sliderInput("support", "Support:",
min=0, max=1, value=0.5),
sliderInput("confidence", "Confidence:",
min=0, max=1, value=0.5),
width=3
),
mainPanel(
plotOutput("plot1")
)
))
Server.R looks like this
library(shiny)
shinyServer(function(input, output) {
output$plot1<-renderPlot({
rules <- apriori(transaction_all[[as.numeric(input$level)]],parameter=list(support=input$support,confidence=input$confidence))
plot(rules, measure=c("support", "lift"), shading="confidence",interactive = TRUE)
})
})
