We can add dropping-lines and colors, using the below code. Scatterplot3d(Girth, Height, Volume, main = "3D Scatterplot of trees dataset") So, the following code generates a 3d graph as shown below the code. ![]() So, to make scatterplots available in 3d, firstly scatterplot3d package must be installed. They make visualization possible in three dimensions which can help to understand the relationship between multiple variables. Pairs(trees, main = "Scatterplot matrix for trees dataset") Implementing the visualization is quite simple, and can be achieved using pairs() function as shown below. R allows us to compare multiple variables at a time because of it uses scatterplot matrices. Plot(Girth, Volume, main = "Scatterplot of Girth vs Volume", xlab = "Tree Girth", ylab = "Tree Volume")Ībline(lm(Volume ~ Girth), col = "blue", lwd = 2) The chart created by the following code shows that there exists a good correlation between tree girth and tree volume. Plot(Girth, Height, main = "Scatterplot of Girth vs Height", xlab = "Tree Girth", ylab = "Tree Height")Ībline(lm(Height ~ Girth), col = "blue", lwd = 2) We have added a trend line to it, to understand the trend, the data represents. The following code generates a simple Scatterplot chart. The chart gives the idea about a correlation amongst variables and is a handy tool in an exploratory analysis. ![]() This plot is a simple chart type, but a very crucial one having tremendous significance. + main = "Histogram of Tree heights with Kernal Denisty plot", ![]() Hist(trees$Height, breaks = 10, col = "orange", The following code does this, and the output is shown following the code. This offers more insights into data distribution, skewness, kurtosis, etc. To understand the trend of frequency, we can add a density plot over the above histogram.
