Introduction

This is a presentation of my Shiny Web App.

In my Shiny Web App I made an interactive plotand i was using a dataset provided by R, mtcars. The dataset contains information about all the fuel consumption and aspects of the automobile design. The mtcars dataset has 32 rows and11 columns and it provides per sort of car several aspects about fuel usage.

Loading in the data and take a look

library(ggplot2)
data <- mtcars
head(data)
##                    mpg cyl disp  hp drat    wt  qsec vs am gear carb
## Mazda RX4         21.0   6  160 110 3.90 2.620 16.46  0  1    4    4
## Mazda RX4 Wag     21.0   6  160 110 3.90 2.875 17.02  0  1    4    4

Some R Code from the server.R

server <- function(input, output) {
  output$plot1 <- renderPlot({
    ggplot(mtcars, x=wt, y=mpg, aes(wt, mpg)) +
      geom_line()+
      labs(title="Plot miles per gallon and weight", x = "Weight", y= "Miles per gallon")
  })
  
  output$info <- renderText({
    paste0("Wt(in 1000 lbs)=", input$plot_click$x, "\nmpg (miles per gallon)=", input$plot_click$y)
  })
}
