Basic Error Bar

library(plotly)

df <- data.frame(x = 1:10,
                 y = 1:10,
                 ymin = (1:10) - runif(10),
                 ymax = (1:10) + runif(10),
                 xmin = (1:10) - runif(10),
                 xmax = (1:10) + runif(10))

p <- ggplot(data = df,aes(x = x,y = y)) + 
    geom_point() + 
    geom_errorbar(aes(ymin = ymin,ymax = ymax)) + 
    geom_errorbarh(aes(xmin = xmin,xmax = xmax))

ggplotly(p)

Margin Error Bar

library(plotly)

population <- data.frame(Year=seq(1790, 1970, length.out=length(uspop)), 
                         Population=uspop, 
                         Error=rnorm(length(uspop), 5))

library(ggplot2)
p <- ggplot(population, aes(x=Year, y=Population, 
                       ymin=Population-Error, ymax=Population+Error))+
  geom_line()+
  geom_point(pch=2)+
  geom_errorbar(width=0.9)

What About Dash?

Dash for R is an open-source framework for building analytical applications, with no Javascript required, and it is tightly integrated with the Plotly graphing library.

Learn about how to install Dash for R at https://dashr.plot.ly/installation.

Everywhere in this page that you see fig, you can display the same figure in a Dash for R application by passing it to the figure argument of the Graph component from the built-in dashCoreComponents package like this:

library(plotly)

fig <- plot_ly() 
# fig <- fig %>% add_trace( ... )
# fig <- fig %>% layout( ... ) 

library(dash)
library(dashCoreComponents)
library(dashHtmlComponents)

app <- Dash$new()
app$layout(
    htmlDiv(
        list(
            dccGraph(figure=fig) 
        )
     )
)

app$run_server(debug=TRUE, dev_tools_hot_reload=FALSE)
