As displayed, our data frame has a categorical variable with 3-factor levels. R assigns factor levels based on alphabetical order. This detail matters when we create dummy variables. Use the dummy_cols() Function to Create Dummy Columns in R If we do not specify the columns from which to ...
Introduction to Factors in R Factors in R programming language is a type of variable that is of limited types in the data set. Factor variables are also resembled as categorical variables. The factor variables in R have a significant impact on data processing and data analysis. Machine learning...
Frequency tables are used by statisticians to study categorical data, counting how often a variable appears in their data set. These are a common way to summarize categorical data in statistics, and R provides a powerful set of tools to create and analyze them. Whether you’re working with su...
When using geom_tile in ggplot2, a heap map can be produced by giving categorical variables to the x and y inputs and a continuous variable to the fill argument of the aes function. Data Science Challenges in R Programming Language (datasciencetut.com) # install.packages("ggplot2") librar...
An obvious solution would be to create a new variable with the study identifier for each row in the data, group by that variable, and then summarise. penguins %>% mutate(StudyName = penguins_raw$studyName) %>% group_by(StudyName) %>% summarise(mean_body_mass = mean(body_mass_g, na...
How to create a rank variable using mutate function of dplyr package in R - A rank variable is created to convert a numerical variable into ordinal variable. This is useful for non-parametric analysis because if the distribution of the numerical variable
How to add a variable description in R - To add a variable description in R, we can use comment function and if we want to have a look at the description then structure call of the data frame will be used. For example, if we have a data frame say df that
