Noticed this didn't make it into the latest release, any plans for the next cycle? This would be incredibly useful as a parameter in read_parquet()

Do you actually want to read an arbitrary subset, or do you want to read

• the beginning of the file?
• the end of the file?
• an interval or rows?
• a couple of intervals?

All of these sound great, I think having a behavior similar to functions like fread() nrows would suffice. This would just read the first n rows or, even better, the firstn rows after a provided skip value (without having to read the entire file into R).
