Trim extreme values in R-CodePudding

I’m working on a large data and I’m trying to trim the extreme values like the ones < 0 and > 8 how can I do that in R?

Atrim = c(0,8)

CodePudding user response：

0:8

trim(0:8)

trim(0:8, trim=0.8)

You were not clear how to handle the outliers. Should they be elimnated or changed to NAs? Here is a simple example that deletes the extreme values:

set.seed(42) # for reproducibility
x <- rnorm(50, 4, 2.5)   # Generate 50 random values
y <- x[x >= 0 & x <= 8]  # Remove outliers
length(y)
# [1] 41  # Nine values were removed.
