Warning: getindex(df::DataFrame, col_ind::ColumnIndex) is deprecated

[Beramos]

This deprecation warning is very unclear to me since the only thing I'm doing is the following,

I don't see why this slicing should lead to deprecation warnings.

Julia version 1.3.1

CSV v0.7.7
DataFrames v0.21.8
GalvanostatLNP v0.1.0
OrdinaryDiffEq v5.42.3

It should print a deprecation because the syntax DF_0Hz_short["<Ewe>/V"] is not supported. It was supported many years ago, and we left a depwarn for some time for the users to accommodate their legacy code. In 2 weeks from now it will error.

The correct syntax is DF_0Hz_short."<Ewe>/V" or equivalently DF_0Hz_short.[!, "<Ewe>/V"] or if you want to copy the vector you extract from the data frame: DF_0Hz_short.[:, "<Ewe>/V"].

Ok thanks, that is clear Op di 10 nov. 2020 13:22 schreef Bogumił Kamiński <notifications@github.com

Maybe as an additional comment - DataFrame is a 2-dimensional object, so for consistency when using indexing syntax df[...] it requires two dimensions to be passed. It is not much more typing but avoids confusion.
