## How to Calculate Standard deviation in R

Standard deviation is “a statistic that measures the dispersion of a dataset relative to its mean and is calculated as the square root of the variance”. To calculate the standard deviation in R, you can use the “sd()” function. The sd() is a built-in function that “accepts the input object and calculates the standard deviation … Read more

## 2 Easy Ways to Convert Data Frame to Data Table in R

To convert a data frame to a data table in R, you can use the “setDT()” or “as.data.table()” function. Method 1: Using the setDT() function The best and easy way to convert a data frame to a data table is to use the “setDT()” function. The setDT() function accepts a data frame as an argument and returns … Read more

## What is the stringAsFactors in R

The stringsAsFactors in R is an argument of the “data.frame()” function. While creating a data frame, there is an argument of stringsAsFactors. The “stringsAsFactors” is a logical argument suggesting whether the strings in a data frame should be treated as factor variables or just plain strings. netflix_data <- data.frame( show_id = c(1:4), show_name = c(“Cabinet of … Read more

## How to Find the Second and Third Lowest Values in Data Frame Column in R

To find the second and third lowest values in R Data Frame Column, you can use the “sort()” method. Example df <- data.frame( name = c(“A”, “B”, “C”, “D”, “E”, “F”, “G”), value = c(51, 12, 41, 21, 20, 81, 11) ) # Second and third lowest values sorted_values_asc <- sort(df\$value, decreasing = FALSE) second_lowest_value … Read more

## How to Find the Second and Third Highest Values in R Data Frame Column

To find the second and third highest values in R Data Frame Column, you can use the “sort()” method. Example # Sample data frame df <- data.frame(name = c(“A”, “B”, “C”, “D”, “E”, “F”, “G”), value = c(51, 12, 41, 21, 20, 81, 11)) # Second and third highest values sorted_values_desc <- sort(df\$value, decreasing = … Read more

## How to Find the Second and Third Lowest Values in R Vector

To find the second and third lowest values in R Vector, you can use the “sort()” method. rv <- c(5, 12, 4, 2, 20, 8, 1) # Second and third lowest values sorted_rv_asc <- sort(rv, decreasing = FALSE) second_lowest <- sorted_rv_asc third_lowest <- sorted_rv_asc cat(“Second lowest value in vector:”, second_lowest, “\n”) cat(“Third lowest value in … Read more
