summary() vs mean()
Forgive what may seem to be a trivial question/problem. Below is some simple R 1.2.1(Windows) code with output. > summary(mammals, digits=10) Name Body.Weight Brain.Weight Red Fox :1 Min. : 3.0 Min. : 26.0 Pig :1 1st Qu.: 35.5 1st Qu.: 138.5 Man :1 Median : 100.0 Median : 406.0 Kangaroo:1 Mean : 761.2 Mean :1000.0 Jaguar :1 3rd

summary gives inaccurate data
Hi, using R64.1 the summary function for simple statistics of a vector gives inaccurate results for the maximum. Example: summary(c(123456,1,2,3)) gives : Min. 1st Qu. Median Mean 3rd Qu. Max. 1.00 1.75 2.50 30870.00 30870.00 123500.00 The Max value ist wrong in a mathematical sense. I've tried with S-Plus, it gives the same result, but this seems

significant figures in summary()
Howdy, Should summary() print answers with different numbers of significant figures, as in the following? > dim(iv) [1] 3000 2 > summary(iv) X1 X2 Min. :-4.15261 Min. :-3.271520 1st Qu.:-0.66188 1st Qu.:-0.671205 Median : 0.01233 Median :-0.008175 Mean : 0.01121 Mean : 0.016815 3rd Qu.: 0.67778 3rd Qu.:

Hello - R-experts, Is there any way with which we can specify the number after decimal point to take.

summary(list) is awesome, but I want more than summary
When I load a table from a data source and run summary() on it, the summary gives me basic summary statistics I'm looking for, and it also discriminates between quantitative and qualitative data and summarizes them accordingly. For example, if I do this: mydata <- read.table("data.txt") summary(mydata) I would get output like this: > summary(mydata) County

Non-visible functions are asterisked
Dear R-Helpers, I suspect I'm about to ask a FAQ, but I haven't been able to find an answer in the FAQ, AItR or an R Site Search. When I look at the methods of summary (below) it says, "Non-visible functions are asterisked". I looked at the help file for summary.princomp, which did not comment on it being non-visible. I ran its help file example, which printed visible output. I
