In R, you can use the
mean() function to calculate the mean of a numerical vector, and the
sd() function to calculate the standard deviation of a numerical vector. Here is an example:
# Create a numerical vector x <- c(1, 2, 3, 4, 5) # Calculate the mean mean(x) # Calculate the standard deviation sd(x)
You can also use the
summary() function to get the mean and standard deviation together with other summary statistics of a numerical vector.
There is also a package called
psych which has more advanced functionality for calculating descriptive statistics, like
describe() function which gives a more detailed summary of the data.
You can install the package by using
install.packages("psych") and load the package by using
