Python Dictionary to R session

Question

I have a python dictionary and want to import it in R.

d = {'X1':[[1,2,3], [10,20]], 'X2':[4,5,6,7]}

In "R" I want it as

> d
$X1
$X1[[1]]
[1] 1 2 3

$X1[[2]]
[1] 10 20


$X2
[1] 4 5 6 7

How can I export/save the python dictionary and read it in R?

Answer 1

1. Use JSON: Importing data from a JSON file into R
2. Use RPY2: http://rpy.sourceforge.net/
3. Use HDF Format: Does anyone have experience opening hdf files in R (Windows OS)?

Answer 2

To read it from an R session you can save your dictionary in JSON format (maybe you will need to install an R library to decode it, like jsonlite or rjson). Otherwise, write it in a table that you can load with read.table, such as CSV format.
