To replace matrix values using ifelse in R, we can follow the below steps −First of all, create a matrix.Then, use ifelse function to replace the values in the matrix.Create the matrixLet’s create a matrix as shown below − Live DemoM

To create a scatterplot between a variable and an equation in R, we can follow the below steps −First of all, create a vectorThen, create the equation and store it in an object.After that, use plot function to create the plot between vector and equation objectCreate the vectorLet’s create a vector as shown below − Live Demox

To divide the data frame row values by row median in R, we can follow the below steps −First of all, create a data frame.Then, use apply function to divide the data frame row values by row median.Create the data frameLet's create a data frame as shown below − Live Demox

To find the maximum value for each row of all matrices 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 and apply function to find the maximum for each row of all matrices.Create the list of matricesUsing matrix function to create multiple matrices and stored them in a list using list function − Live DemoM1

To find the maximum value of all matrices 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 unlist and lapply function to find the maximum of all matrices.Create the list of matricesUsing matrix function to create multiple matrices and stored them in a list using list function − Live DemoM1

To subset rows that contains maximum depending on another column in R data frame, we can follow the below steps −First of all, create a data frame with one numerical and one categorical column.Then, use tapply function with max function to find the rows that contains maximum in numerical column based on another column.Example1Create the data frameLet's create a data frame as shown below − Live Demox

To divide matrix row values by row maximum 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 maximum.Create the matrixLet’s create a matrix as shown below − Live DemoM

To expand a matrix rows by its index position in R, we can follow the below steps −First of all, create a matrix.Then, use rep and seq_len function with nrow to expand the matrix rows by their index position.Create the matrixLet’s create a matrix as shown below − Live DemoM

To create a boxplot using ggplot2 with aes_string in R, we can follow the below steps −First of all, create a data frame with one string and one numerical column.Then, use aes_string function of ggplot2 package to create the boxplot.Create the data frameLet's create a data frame as shown below − Live DemoX

To create a bar chart for single vector using ggplot2 in R, we can follow the below steps −First of all, create a vector and melt it using melt function of reshape2 package and save the melted data.Then, create the bar chart with melted data using ggplot2.Create the vector and melt itCreating the vector and using melt function of reshape2 to melt the data in vector −x
