R help - Feb 2010 - Count between interval

Hi all,

I take a simple dataset like this:

-1.3
1
-1.5
-1
1.5
-2.5
3
-0.5

Now I want to count how many values there are between -2 and 2.

The answer here would be 6.

Can anyone do this with R?

Thank you in advance.

Hi,
ab<-read.table(header=F,file=textConnection("-1.3
1
-1.5
-1
1.5
-2.5
3
-0.5"))

length(which(ab >=-2 & ab<=2))

Hi,

Here is a suggeston:

> x <- c(-1.3, 1, -1.5, -1, 1.5, -2.5, 3, -0.5)
> sum(x >=-2 & x<=2)
[1] 6

And as long as the interval is symmetric about zero:

sum(abs(x) <= 2)
[1] 6
