How to calculate the average and median in R language
This article mainly introduces how to use R language to calculate the average and median related knowledge, the content is detailed and easy to understand, the operation is simple and fast, and has a certain reference value. I believe you will gain something after reading this article on how to calculate the average and median in R language. Let's take a look.
Mean () calculates the average by finding the sum of the data set and dividing it by the total sum of the sum number to get the average function mean () which is used to calculate the average in R language. The basic syntax used to calculate the average in R is-mean (x, trim = 0, na.rm = FALSE,...).
Mean () to find the average
The average value is obtained by finding the sum of the data set and dividing it by the total sum of the sum number.
The function mean () is used to calculate the average in the R language.
Grammar
The basic syntax used to calculate the average in R is-
Mean (x, trim = 0, na.rm = FALSE,...)
The following is a description of the parameters used-
X is the input vector.
Trim is used to discard observations from both ends of the sort vector.
Na.rm is used to remove missing values from the input vector.
Apply pruning option
When the trim parameter is provided, the values in the vector are sorted and the required observations are subtracted from the calculated average.
When trim = 0.3, the three values from each end are subtracted from the calculation to find the mean.
Apply NA option
If there is a missing value, the average function returns NA.
To remove missing values from the calculation, use na.rm = TRUE. This means removing the na value.
Median () to find the median
The innermost value in the data series is called the median. Use the median () function in the R language to calculate this value.
Grammar
The basic syntax for calculating the median in R language is-
Median (x, na.rm = FALSE)
The following is a description of the parameters used-
X is the input vector.
Na.rm is used to remove missing values from the input vector.
This is the end of the article on "how to calculate the average and median in R language". Thank you for reading!
