Remove values from a vector based on a condition

Question

Suppose I have a vector x <- c(-10,10) and I want to remove the values from the vector which absolute value is larger than 8, how can I achieve that?

I do not want to delete the values by knowing the exact values, which would be c(-10, -9 , 9 , 10), like in this post: How to delete multiple values from a vector?

Answer 1

this solve your problem:

x <- x[abs(x) <= 8]

Answer 2

You have many ways to make it

x <- x[abs(x) <= 8]

or

x <- subset(x,abs(x)<=8)

or

x <- x[-which(abs(x)>8)]

or

x <- na.omit(ifelse(abs(x) > 8,NA,x))
