Take part of string

how do I get part of a string from a field in the dataframe

I don’t know what you are looking for exactly, but maybe this might be helpful:

using DataFrames, VegaDatasets
tmp = DataFrame(dataset("stocks"))
tmp[!, :smaller_string] .= SubString.(tmp.symbol,1,2)

note that symbol is the name of the column in the dataframe.
The VegaDatasets is loaded because I am too lazy to come up with a dataframe on my own.


helped me a lot … thanks
