In Jupyter notebook, how to deal with the R function argument that contain special symbol?

[zhanglab2008]

Hi, great work!
I don't know how to escape the special character in the arguments when I used RCall in jupyter notebook. Here is an example:

@rimport Seurat as seu
seu.DimPlot(object=R"girlom", label=true, label.size=6)

In this example, label.size has a special symbol ".", which is allowed in R. When I run this in Julia, however, it gets me this error:

syntax: invalid keyword argument name "label.size" around In[19]:1

Stacktrace:
 [1] top-level scope
   @ In[19]:1
 [2] eval
   @ ./boot.jl:360 [inlined]
 [3] include_string(mapexpr::typeof(REPL.softscope), mod::Module, code::String, filename::String)
   @ Base ./loading.jl:1094

Do you have any ideas how to get around this?
Many thanks!!!
