HJ,
You don't provide any reproducible code, so I had to make up my own.
dat <- data.frame(a=letters[1:5], x=c(20110911001084, 20110911001084,
20110911001084, 20110911001084, 20110911001084),
y=c(2.10004e+12, 2.10004e+12, 2.10004e+12, 2.10004e+12,
2.10004e+12))
In my example, the long numbers print out without scientific notation.
dat
a x y
1 a 20110911001084 2100040000000
2 b 20110911001084 2100040000000
3 c 20110911001084 2100040000000
4 d 20110911001084 2100040000000
5 e 20110911001084 2100040000000
I can make it print with scientific notation using the digits argument to
the print() function.
print(dat, digits=3)
a x y
1 a 2.01e+13 2.1e+12
2 b 2.01e+13 2.1e+12
3 c 2.01e+13 2.1e+12
4 d 2.01e+13 2.1e+12
5 e 2.01e+13 2.1e+12
What is your default number of digits?
getOption("digits")
