I am working on it, but I have a question concerning strings and lists in elisp. In the function org-babel-execute:R it says: ,---- | (inside | (list (org-babel-expand-body:R body params graphics-file))) `---- I now want to convert "inside" to a comma separated string. I am doing now the following: ,---- | (replace-regexp-in-string "\n" ", " (format "%s" inside)) `---- but this does not look elegant to me, as I am converting inside to a string and then do a replace. There is the function mapconcat, but I don't get it to work: ,---- | (replace-regexp-in-string "\n" ", " (format "%s" inside)) | "( createOrgVariablesEnvironment(), plot(1))" | | (mapconcat 'identity inside ", ") | " createOrgVariablesEnvironment() | plot(1)" `---- What am I missing?
