Hi,
I want to perform t-test in R for each individual car. Here is what i have.
Is there a way i can test each car?
The original table (test.csv)
Car Tester2 Tester2 Controller1 Controller2
Audi 0.56 0.9 0.5 0.9
Toyota 0.2 0.9 0.9 0.2
Honda 0.5 0.9 0.1 0.5
BMW 0.2 0.3 0.5 0.7
> cars<-read.table("c://test.csv",header=T,sep=",",
+ skip=2,comment.char="")
> cars
Toyota X0.2 X0.9 X0.9.1 X0.2.1
1 Honda 0.5 0.9 0.1 0.5
2 BMW 0.2 0.3 0.5 0.7
> head(cars)
Toyota X0.2 X0.9 X0.9.1 X0.2.1
1 Honda 0.5 0.9 0.1 0.5
2 BMW 0.2 0.3 0.5 0.7
why is R only showing two cars when i type head?
many thanks.
