A) It's kind of good that it "works" right now, but I don't think we are safe in this example. B) I bet this will break our eventual summary statistics C) In pandas, this is also a problem:
Although, tbf - this is not really a valid data.frame name
> names(example)
[1] "" "age" "age "
> example[""]
Error in `[.data.frame`:
! undefined columns selected
Show Traceback
> tibble::tibble(example)
Error in `env[[name]] <- x`:
! attempt to use zero-length variable name
Show Traceback
But it does work in Pandas
# blank names
import pandas as pd
num_print = pd.DataFrame({'Name':['Ashika', 'Tanu', 'Ashwin', 'Mohit', 'Sourabh'],
'': [100000000, 100025000, 210000000, 190000000, 0.100000000115151]})
>>> num_print[""]
0 100000000.0
1 100025000.0
2 210000000.0
3 190000000.0
4 0.1
Name: , dtype: float64
Also even works for summary statistics:
# blank names
import pandas as pd
num_print = pd.DataFrame({'Name':['Ashika', 'Tanu', 'Ashwin', 'Mohit', 'Sourabh'],
'age': [100000000, 100025000, 210000000, 190000000, 0.100000000115151]})
num_print.rename(columns = {'age': '', 'Name': ''}, inplace=True)
Several years ago I spent a lot of time ruminating on names in the R world, most especially in the context of data.frames. I'll link the write-up of where all of that ended up, in case ideas or vocabulary are helpful in working out what we're going to support here:
@EmilHvitfeldt I split off your other example of leading/trailing whitespace into a separate issue: https://github.com/posit-dev/positron/issues/3089

Steps to reproduce the issue:
What did you expect to happen?
I don't have a good solution, but I still have nightmares from the time I had a dataset with column names, padded with spaces
Were there any error messages in the output or Developer Tools console?
Nope
