result.mean <- mean(x,trim = 0.3)
print(result.mean)
When we execute the above code, it produces the following result:
Applying NA Option
If there are missing values, then the mean function returns NA.
To drop the missing values from the calculation, use na.rm = TRUE. which means removing the NA values.
Example
Enter the following code snippet in the script panel:
# Creating a vector.
x <- c(12,7,3,4.2,18,2,54,-21,8,-5,NA)
# Finding mean.
result.mean <- mean(x)
print(result.mean)
# Find mean dropping NA values.
result.mean <- mean(x,na.rm = TRUE)
print(result.mean)
When we execute the above code, it produces the following result:
