To return a logical value for a t test based on 0.05 level of significance in R, we can follow the below steps −First of all, create a data frame with one column.Apply t.test function with ifelse to return logical value based on 0.05 level of significance.Example1Create the data frameLet's create a data frame as shown below − Live Demox
To find the maximum value in each matrix stored in an R list, we can follow the below steps −First of all, create a list of matrices.Then, use max function along with lapply function to find the maximum of each matrix.Create the list of matricesUsing matrix function to create multiple matrices and stored them in a list using list function − Live DemoM1
To divide matrix row values by row median in R, we can follow the below steps −First of all, create a matrix.Then, use apply function to divide the matrix row values by row median.Create the matrixLet's create a matrix as shown below − Live DemoM
To save a vector in R as CSV file, we can follow the below steps −First of all, create a vector.Then, use write.csv function to save the vector in CSV file.Example 1Let’s create a vector as shown below − Live Demox
To create a table of frequency for range of values in an R data frame column, we can follow the below steps −First of all, create a data frame.Then, use table function with cut function to create the table of frequency for range of values.Example 1Create the data frameLet's create a data frame as shown below − Live Demox
To create density plot with manually setting the colors of categories, we can follow the below steps −Frist of all, create a data frame.Load ggplot2 package and creating the density plot for the categories.Create the density plot for the categories in the data frame by using scale_fill_manual function.Create the data frameLet's create a data frame as shown below − Live Democategories
To find the row minimum excluding zero in R data frame returning 0 if all 0, we can follow the below steps −First of all, create a data frame.Then, find the row minimum by excluding zero using if function with apply function.Example1Create the data frameLet's create a data frame as shown below − Live Demox1
To create a horizontal line in ggplot2 graph with different in R, we can follow the below steps −First of all, create a data frame.Then, create a plot using ggplot2 using geom_hline function having horizontal line.After that, create the same plot with line color defined with col argument.Create the data frameLet's create a data frame as shown below − Live Demox
To perform Friedman test in R, we can follow the below steps −First of all, create a matrix.Then, use friedman.test function to perform the Friedman test.Example1Create the matrixLet's create a data matrix as shown below − Live DemoFirst
To divide matrix row values by row sum in R, we can follow the below steps −First of all, create a matrix.Then, use apply function to divide the matrix row values by row sum.Create the matrixLet’s create a matrix as shown below − Live DemoM
