remove filter

subset is preferred to filter in DataFrames 1.0, so I used lm as an example of using dataframe as a second argument.

Thanks, that might be a good idea to change. I think I tweaked the examples before to fit into the column width on github without horizontal scrolling, could be that this doesn't fit anymore with lm. I'm also not sure if I find that function a bit too specialized, don't know how widely used it is. But it is a good example of needing a second argument. What other functions would offer themselves instead of filter?

Ok, we can use CSV.write
