They are probably the same. It isjust that summary is printing out 4
significant digits. Try:
options(digits = 20)
FYI, the default summary method also has its own digits argument.

Hi,
I summary() a variable with 409908 numeric observations. The variable is
part of a data.frame. The problem is that the min and max returned by
summary() do not equal the ones returned by min() and max(). Does anybody
know why that is?
min(data$vc)
[1] 15452
max(data$vc)
[1] 316148
summary(data$vc)
Min. 1st Qu. Median Mean 3rd Qu. Max.
