Hi,
I haven’t found the way to select a specific SubDataFrame in a Grouped DataFrame.
Let’s say you have the following dataframe
df = DataFrame(A = rand(5), B = ["type1", "type2", "type1", "Type3", "type2"])
that you group by with column B
dfg = groupby(df,:B)
If you want to acces to one subdataFrame you can use indexing
dfg[1]
But without checking the value in dfg[1] of column B, you don’t know which one is it…
Is there a way to say I want the subdataFrame corresponding to B = “type2” ? Something like
dfg[B = "type2"]
or directly
dfg[Symbol("type2")]
Thanks for your help.
