To change the color of line of a plot created for an xts object in R, we can follow the below steps −First of all, create a data frame.Then, convert this data frame into an xts object.Create the plot for the data in xts object with default color.Then, create the plot for the data in xts object with different colorCreate the data frameLet's create a data frame as shown below −Dates

To create facetted plot with facets in horizontal direction using ggplot2 in R, we can follow the below steps −First of all, create a data frame.Then, create the facetted plot using facet_grid function of ggplot2 package.Use facet_grid function with reversed value of categorical column to create the facetted plot with facets in horizontal direction.Create the data frameLet's create a data frame as shown below − Live Demox

To create horizontal line for Y variable at median in base R plot, we can follow the below steps −First of all, create two vectors and plot them.Create the horizontal line at median using abline function.Create the vectors and plot themLet’s create two random vectors and plot them as shown below −Example Live Demox

To create vertical line for X variable at median in base R plot, we can follow the below steps −First of all, create two vectors and plot them.Create the vertical line at median using abline function.Create the vectors and plot themLet’s create two random vectors and plot them as shown below −Example Live Demox

To define points outside the R data frame and draw them in ggplot2 graph, we can follow the below step −First of all, create a data frameThen, create the scatterplot using geom_point function of ggplot2 package.Create the scatterplot with data outside data frame using data.frame inside geom_point.Create the data frameLet's create a data frame as shown below − Live Demox

To create a ggplot2 graph in R without showing values, we can follow the below steps −First of all, create a data frame.Then, create the graph using ggplot2.Create the graph using ggplot2 without providing the function for the plot.Create the data frameLet's create a data frame as shown below − Live Demox

To delete lines after creating a line chart with points in base R we would need to create the points chart only, therefore, we can follow the below steps −First of all, create two vectors and create the line chart with points.Now, again create the line chart but without pointsCreate the vectors and line chart with pointsUse plot and lines function to create the line chart with points as shown below − Live Demox

To create facetted scatterplot with scale of X-axis based on the numerical values corresponding to grouping column in R, we can follow the below steps −First of all, create a data frame having at least one grouping column and two numerical columns.Create the facetted scatterplot based on the grouping column.Create the facetted scatterplot based on grouping column with X-axis scale based on corresponding values in numerical columns.Create the data frameLet's create a data frame as shown below − Live Demox

To display two equal signs using ggplot2, we can follow the below steps −First of all, create a data frame.Create a scatterplot(you can create any other plot).Display two equal signs using annotate functionCreate the data frameLet's create a data frame as shown below − Live Demox

To display regression intercept using model in a plot created by ggplot2, we can follow the below steps −First of all, create the data frame.Use annotate function of ggplot2 to create the scatterplot with regression intercept displayed on the plot.Check the regression intercept.Create the data frameLet's create a data frame as shown below − Live Demox
