[SOLVED] I get Error: invalid version specification ‘0,2’ when I use the function dm

I get Error: invalid version specification ‘0,2’ when I use the function dm_draw() in r

I want to use the function dm_draw() to visualize a dm object but when I ran the command I get the error message " Error: invalid version specification ‘0,2’". I've tried the code included in the vignette "Visualizing dm objects" (https://cran.r-project.org/web/packages/dm/vignettes/tech-dm-draw.html) and I get the same error message when I run the dm_draw() function.

library(dm)
library(dplyr)
flights_dm_w_many_keys <- dm_nycflights13(color = FALSE)
dm_draw(flights_dm_w_many_keys)

I'm using dm version 0.2.7 and DiagrammeR 1.0.8. R version 4.1.2

I'm looking for a solution to visualize a dm object, it can be also different from dm_draw(). I hope someone can help me to get that done. Sorry for my broken English and thanks for your time, any type of help is appreciated.

Solution

You can use this code:

       library(dm)
       library(dplyr)
       library(DiagrammeR)
       library(DiagrammeRsvg)
       
       # Use this function
       dm_draw_svg = function(dm,...) {
         if (!requireNamespace("DiagrammeRsvg", quietly = TRUE)) {
           stop(
             "Package \"DiagrammeRsvg\" must be installed to use this function.",
             call. = FALSE
           )
         }
         
         dm::dm_draw(dm = dm, ...) %>%
           DiagrammeRsvg::export_svg() %>%
           htmltools::HTML() %>%
           htmltools::html_print()
       }
       
       flights_dm_w_many_keys <- dm_nycflights13(color = FALSE)
       # plot
       dm_draw_svg(flights_dm_w_many_keys)

Output:
