CALCULATE STANDARD ERROR R CODE

We can either use the std.error() function provided by the plotrix package, or we can easily create a function for the same. It is relatively simple in R to calculate the standard error of the mean. The formula for standard error of mean is the standard deviation divided by the square root of the length of the data. It tells us how the sample deviates from the actual mean, unlike standard deviation, which is a measure of the amount of dispersion in the data. In the world of statistics, the standard error of mean is a very useful and important term.
