Syntax: mean(x, na.rm) Parameters: x: Numeric Vector na.rm: Boolean value to ignore NA value Example 1: # R program to calculate # Arithmetic mean of a vector # Creating a numeric vector x1 <- c(1, 2, 3, 4, 5, 6) x2 <-c(1.2, 2.3, 3.4, 4.5) x3 <- c(-1, -2, -3, -4, -5, -6) # Calling mean() function mean(x1) mean(x2) mean(x3) Output: [1] 3.5 [1] 2.85 [1] -3.5 Example 2: # R program to calculate # Arithmetic mean of a vector # Creating a numeric vector x1 <- c(1, 2, 3, NA, 5, NA, NA) # Calling mean() function # including NA values mean(x1, na.rm = FALSE) # Calling mean() function # excluding NA values mean(x1, na.rm = TRUE) Output: [1] NA [1] 2.75 Like Article Suggest improvement Next Calculate the Median Absolute Deviation in R Programming - mad() Function Share your thoughts in the comments Add Your Comment Please Login to comment...
