# Create R Scatter Plot using Lattice package If the requirement is to import R Programming data from external files, I suggest you refer R Read CSV article to understand the CSV file import. For this, we are using the diamonds data set, which is provided by the R Studio. #SCATTER PLOT R STUDIO HOW TO#In this example, we show how to use this xyplot function in the lattice package to create a Scatter Plot. Panel = lattice.getOption("panel.xyplot"),ĭ = lattice.getOption(""),ĭefault.prepanel = lattice.getOption(""),įor this, we are going to use the diamonds data set that is provided by the R, and the data inside this dataset is: Create Lattice Scatter Plot in R )Īnd the complex syntax of lattice Scatter plot is: xyplot(x, data,Īllow.multiple = is.null(groups) || outer, Let us see how to Create Lattice Scatter Plot in R Programming, Format its color, shape, etc., with an example. The syntax to draw the Lattice scatter chart, or Lattice Scatter Plot is xyplot(x, data. You can call this R Scatter Plot as a scatter chart, scatter graph, scattergram, or scatter diagram.įor example, to visualize the Salary against Experience, use this Scatter Plot. This lattice scatters plot in R is very useful to visualize the relationship between two sets of data. Second, when we add the text in the third line of the code, we do not have pos=1, because we want to place the labels exactly where the points are.The lattice package in R Programming provides xyplot to draw Scatter Plot. There are two differences in the code: First, we add type="n" to create the scatter plot without actually drawing any circles (an empty plot if you will). The scatter plot on the right is similar, but here we actually plot the labels instead of the dots. Plot(policy ~ perfor, bty="n", ylab="Policy Indicator", xlab="Performance", main="Policy and Performance") The argument pos=1 is there to tell R to draw the label underneath the point with pos=2 (etc.) we can change that position. To add the labels, we have text(), the first argument gives the X value of each point, the second argument the Y value (so R knows where to place the text) and the third argument is the corresponding label. Then we add the trend line with abline() and lm(). The third line here creates a string of characters “A” to “Y”, these are the labels!Ĭanton = sapply(65:89, function(x) rawToChar(as.raw(x)))įor the scatter plot on the left, we use plot(). In this example, we have 25 observations, for 25 units I call “cantons”. #SCATTER PLOT R STUDIO CODE#It is conventional to put the outcome variable on the Y axis and the predictor on the X axis, but in this example there’s no relationship to reality anyway… The reason I chose min and max values for the random variables here is that I jotted down this code as an explanation for a replication. In this fictitious example, I look at the relationship between a policy indicator and performance. Since the data are random, your plots will look different. The basic function is text(), and here’s a reproducible example how you can use it to create these plots: Adding text to a scatter plot in Rįor the example, I’m creating random data. Adding text labels to a scatter plot in R is easy.
