I am trying to get the max, min and mean of a column in a data frame. When i use max, min and mean I get some values which are different from the values when I used, summary()
> max(count1,na.rm=TRUE)
[1] 202034
> min(count1,na.rm=TRUE)
[1] 0
> mean(count1,na.rm=TRUE)
[1] 8498.78
> summary(count1,na.rm=TRUE)
Min. 1st Qu. Median Mean 3rd Qu. Max. NA's
0 1555 3668 8499 8535 202000 58297
The summary.default
function has a digits
argument:
summary(object, ..., digits = max(3, getOption("digits")-3))
Since the default getOptions("digits")
is 7
, you get only 4
digits. Everything after that is rounded (with a call to signif()
). You can change as proposed by user20650 setting eg
options(digits=10)
Or if you want the change just for this particular call:
summary(count1, digits = 10)
