Different values when using summary () and max, min and mean in R
I am trying to get the max, min and mean of a column in a dataframe. When I use max, min and mean, I get some values that differ 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
0 1555 3668 8499 8535 202000 58297

The function summary.default
has an argument digits
:
summary(object, ..., digits = max(3, getOption("digits")-3))
Since the default getOptions("digits")
is 7
, you only get numbers 4
. Everything is then rounded off (with a challenge signif()
). You can change as suggested by user20650 .
options(digits=10)
Or, if you only want to change for that specific call:
summary(count1, digits = 10)
