Nice comparison!
Just a remark, you didn't really give the pandas alternative for your first case (to access columns by name), so maybe add that? (df[, c("a", "c", "e")] -> df[["a", "c", "e"]])

@jorisvandenbossche Thanks! I'll add that.

[jorisvandenbossche]

Actually, I think you can just do: df.iloc[:, r_[:10, 24:30, 39, 49:100]]?

Another alternative (without the somewhat strange r_ function) is the very basic usage of range (but somewhat longer):
df.iloc[:, range(10) + range(24, 30), range(49, 100)]

@jorisvandenbossche Awesome. I didn't know that.

[jorisvandenbossche]

I also just discovered it now :-) So certainly check if it is the same.

[cpcloud]

It is, just checked it. Here's the SO question that inspired this addition to the docs.

@jorisvandenbossche Any more comments?

[jorisvandenbossche]

Nope, thanks! Maybe just check tomorrow the rendered dev doc to see if everything looks good
