Way to add new template in R plot node or save adaptions?

[johnprime]

Dear All

I really like using the R plot node (with the standard data input) for generating more advanced plots, but would like to adapt the plots and then save them as a new template in that node.
Or add the full RGG template code to another scripting node to run in the future as needed via the GUI.
Is there a way to do this in this or another node?

Even trying to apply or OK changes in a template gives me a warning for Invalid settings: java.lang.Null PointerException but with little indication what it doesn’t like.

I wonder if this past thread relates to the same problem - QQ plot

Many thanks for any thoughts and advice

You could save all kinds of information from R in RDS files. You could try and store such a template and maybe settings in an RDS file and read them back later.

Thanks - @mlauber71 - you’ve clearly spent a lot of time generating valuable content around R - KNIME integration which is great!

Regarding the workflow you linked above I found I was having to create graphics and a data folders in the appropriate path for the Table to R node to work otherwise it was giving me an “error in the R code - cannot open the connection” message.

I take it there isn’t a way to adapt the RGG based templates and then save them with a different name to then be used routinely in the R plot node or any other for that matter (e.g. R View (workspace or Table)?

Or is there an alternative way to create adaptable plots while incorporating KNIME color, shape and size models?

Thanks again

The example was meant to lead to new ideas. I wanted to show that you could store information from one R session and read it back in another one.

If you could provide a full example one could see if there might be a way to transfer the information.

There was a debate about KNIME color manager and how to transport the information to python, maybe a similar thing is possible with R.

Python View and Color Manager

I am not exactly sure how one would store a piece of colour information with a Pandas data frame. I constructed a script that would extract the colour settings from the KNIME colour manager and store them as a Python dictionary object and save that as a pickle file. [image] This dictionary will later be loaded back into the Python script and be used as a palette with seaborn or as a colour dictionary for matplotlib. [image] OK admittedly not the most straightforward solution but hey it can …
