Hello All,
I am new in R, so please excuse the basic questions.
But how do you change the number of digits to be displayed?
I have done the following, hoping I will get 4 decimal places in my
answer:
vars <- var(cbind(Sepal.l,Sepal.w,Petal.l,Petal.w))
print(vars,digits=4)
But as seen below from the output, that is not the case
> print(vars,digits=4)
Sepal.l Sepal.w Petal.l Petal.w
Sepal.l 0.68569 -0.04074 1.2743 0.5163
Sepal.w -0.04074 0.19363 -0.3287 -0.1212
Petal.l 1.27432 -0.32873 3.1163 1.2956
Petal.w 0.51627 -0.12124 1.2956 0.5810
How come the Sepal.l and Sepal.w does not come with only 4 decimal places.
Can someone tell me where I am going wrong?
Also if I use the "options(digits=4)"- How do I make it to go back to
Normal or default, which is 7 in this case.?
