maybe describe
method should be for whole Dataframe and describeColumn
sholud take columnName
and do what current describe
does? @piotrMocz @kustosz ?
from dataframes.
Case: user has a table, wants to fill nulls in each column with a mean value for that column
from dataframes.
The thing I have very strong feelings about:
the Table
class should expose the read<Format>
method. Please keep in mind that we're not targetting expert programmers or even hobbyist programmers, but "data profesionals".
Table.readCSV
is a method that gives you a table from a CSV file. Table.readXLS
is a method that gives you a table from an Excel file. And so on. Accidentally, this is exactly how pandas
does it. Advantages:
- single import for
Table
read and forTable
processing - "ideological" compatibility with
pandas
- hides the implementation details and makes the API dead simple
Currently you write CSVParser.readFile
. Let's look at the drawbacks:
- when processing data, you need another entity: some parser. I wouldn't want to have to know about some parsers when all I want to do is to read a dataframe from file
- one more concept to keep track of
- one more import
All in all, I suggest we at least add the Table.readCSV = CSVParser.readFile
alias.
Like, really, please 😅

All non-user facing functions should have _
prefix
from dataframes.
@piotrMocz what do you rthink about #57 in context of reading/writing files?
from dataframes.
Moreover, the toInt
method should be named toEnum
from dataframes.
Table.fromFile
should have better name (more descriptive)
from dataframes.
removeColumn
-> removeByIndex
from dataframes.
keep
as opposite to remove
from dataframes.
corr
-> correlations
corrWith
-> correlationsWith
from dataframes.
change generated names from CORR_WITH_foo
to corr_with_foo
from dataframes.
sort -> sortMultiple
sort Descending by default
sort config (?)
from dataframes.
