I'm closing this fow now. We're working on a new CSV implementation based on Deephaven CSV https://github.com/Kotlin/dataframe/issues/827 since it's faster and lighter, however this also doesn't allow Regexes for delimiter...
@kosak We're not developing our own CSV library. We're simply replacing our Apache commons CSV integration in DataFrame with Deephaven's :) exactly for the reasons you mentioned; performance, type inference,...
https://github.com/deephaven/deephaven-csv/issues/212 is merged :) We'll add it in https://github.com/Kotlin/dataframe/pull/903. Simply set `hasFixedWidthColumns = true` and the column widths are determined by the width of the headers + spaces. You can...
These tests are `@Ignore`d. Actually, most of them fail because `DataFrame.read("titanic.csv"): dataframe/core/titanic.csv (No such file or directory)`. And this is by design I think. They're not supposed to run, they're...
Hmm that I cannot reproduce, the tests compile and run fine on my end :/ Maybe someone else can reproduce it?
That's probably why it was hidden
probably yes. For advanced stuff users can simply parse it using their own parser, export to string and feed it to DF again
Definitely! It depends a bit from where you want to disable this. If you're reading from CSV, for instance, you can supply a `colTypes = mapOf("yourColName" to ColType.String)`, this will...
I think this is the intended behavior. The key of the group is something temporary and usually consists of columns already in the DF. We are working on a way...
maybe a `concatWithKeys()` would be a nice addition?
