How add more information in tooltip cloude in ggiraph packages in R?
ggiraph, r, shiny, tooltip
Solution
You can use `paste0` to get the tooltip with all the values as follows:
df$tooltip <- c(paste0("Name = ", df$col_C, "\n Column A = ", df$col_A, "\n Column B = ", df$col_B))
Then instead of `geom_point_interactive(tooltip=df$col_C)` you can use `geom_point_interactive(tooltip=df$tooltip)`
Hope it helps!
Problem
I would like to create a cloud which shows information about the point using tooltip in ggiraph packages. I can create a cloud with only one information (from one column), but I would like to add information from three columns. Below I added a picture what I want to achieve and code. The code is correct but on the plot is information from only one column. Picture shows what I want to achieve ``` #lib. library(ggiraph) library(ggplot2) library(shiny) #create data frame col_A=c(123,523,134,543,154) col_B=c(100,200,300,400,500) col_C=as.character(c("food_1", "food_2", "food_3", "food_4", "food_5")) df=data.frame(col_A, col_B, col_C) df$col_C <- as.character(df$col_C) #ui. ui <- fluidPage( ggiraph::ggiraphOutput("plot1")) #server server <- function(input, output) { gg <- ggplot(data = df ,aes(x = col_A, y = col_B)) + geom_point_interactive(tooltip=df$col_C) # I would like to plot like this: geom_point_interactive(tooltip=c(df$col_A, df$col_B, df$col_C)) # but i causes error: Aesthetics must be either length 1 or the same as the data (5): tooltip output$plot1 <- renderggiraph({ ggiraph(code= print(gg))}) } shinyApp(ui = ui, server = server) ```
