Reshape table using Pivot

Hello I’m trying to reshape a table like the following example from: pydata Pandas Reshaping So far I have tried with the following code:

df = new dataForge.DataFrame({columns: {"foo": ["one", "one", "one", "two", "two","two"],
                                        "bar": ["a", "b", "c", "a", "b", "c"],
                                        "baz": [1, 2, 3, 4, 5, 6]}})
df = df.setIndex("foo").dropSeries("foo").bake()
df.pivot("bar", "baz", dataForge.Series.sum).toString()

which yields

__index__  bar  baz
---------  ---  ---
0          a    5  
1          b    7  
2          c    9  

But it seems to just ignore the index and group by the “baz” column. I have tried different variations but still I cant get it to work.

How can I achieve what is shown on the picture above?

I am exploring the same problem today using data-forge. I think this chapter explains well the similar scenarios and rationales of pivot in R’s tidyverse https://r4ds.had.co.nz/tidy-data.html

Thanks for the info. I’m hoping to spend more time this year expanding Data-Forge, so stay tuned.

Although if you’d like to contribute to improving this code library, please do!
