To create a bar plot in R filled with color palette in RColorBrewer package, we can follow the below steps −First of all, create a vector.Create the bar plot with color palette in RColorBrewer package.Example 1Let’s create a vector as shown below − Live Demox

The different color palettes can be found by using display.brewer.all() function. Each of the palette has different colors. There are three types of palettes defined with names equential, diverging, and qualitative. They are defined for specific uses as written below −Sequential palettes are suited to ordered data that progress from low to high.Diverging palettes put equal emphasis on mid-range critical values and extremes at both ends of the data range.Qualitative palettes are best suited to representing nominal or categorical data.Find the color palettes in RColorBrewer packageInstalling and Loading RColorBrewer package and finding the different color palettes −install.packages("RColorBrewer") library(RColorBrewer) display.brewer.all()On executing, ...

To manually set the color of each bar in base R bar plot, we can follow the below steps −First of all, create a vector.Then create the bar plot with col argument.Example 1Create the vectorLet’s create a vector as shown below − Live Demox

To create a graph in base R with multiple shades of a particular color, we can follow the below steps −First of all, create color shades using colorRampPalette then plot a graph.Use the color shades to create the graph.Example 1Create the color shadesUsing colorRampPalette function to create the color shades between red and darkred color then creating the plot − Live DemoColor

To display axes ticks and labels inside the plot using ggplot2 in R, we can follow the below steps −First of all, create a data frame.Then, create a plot using ggplot2.After that create the same plot with theme function to change the position of axes ticks and labels.Create the data frameLet's create a data frame as shown below − Live Demox

To divide the row values by row variance in R’s data.table object, we can follow the below steps −First of all, create a data.table object.Then, use apply function to divide the data.table object row values by row variance.Create the data.table objectLet’s create a data.table object as shown below −library(data.table) x

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

To divide data frame row values by row variance 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 variance.Create the data frameLet's create a data frame as shown below − Live Demox

To divide data frame row values by row maximum excluding 0 in R, we can follow the below steps −First of all, create a data frame.Then, use apply function and if else function to divide the data frame row values by row maximum excluding 0.Create the data frameLet's create a data frame as shown below − Live Demox

imageaffinematrixget() is an inbuilt function in PHP that is used to get an affine transformation matrix. This function is often used in linear algebra and computer graphics.Syntaxarray imageaffinematrixget(int $type, mixed $options)Parametersimageaffinematrixget() accepts only two parameters: $type and $options.$type − The $type parameter specifies the integer to IMG_AFFINE constants.IMG_AFFINE_TRANSLATEIMG_AFFINE_SCALEIMG_AFFINE_ROTATEIMG_AFFINE_SHEAR_HORIZONTALIMG_AFFINE_SHEAR_VERTICAL$options − If type is IMG_AFFINE_TRANSLATE or IMG_AFFINE_SCALE, options has to be an array with keys x and y, both having float values. If type is IMG_AFFINE_ROTATE, IMG_AFFINE_SHEAR_HORIZONTAL or IMG_AFFINE_SHEAR_VERTICAL, options has to be a float specifying the angle.Return ValuesIt returns an affine transformation matrix, an array with keys from 0 to 5 ...
