Hi all, I have a list with a numerical column "cum_hardreuses". By coincidence I discovered this:
max(libs[,"cum_hardreuses"])
[1] 1793
summary(libs[,"cum_hardreuses"])
Min. 1st Qu. Median Mean 3rd Qu. Max.
1 2 4 36 14 1790
(note the max value of 1790) Ouch this is bad! Anything I can do to remedy
this? Known bug?
No, it's a feature! See ?summary: printing is done up to 3 significant digits by default.
Unfortunately, '1790' is printed with *four* significant digits, not three. The correct representation with three significant digits would have to employ scientific notation, 1.79e3.
