Hello, I have a double 10x160260, and I would like to do a PCA of the 10 different variables, and to obtain the plot of PC1 and PC2. How is this possible knowing the significqnt size of my dataset? Thanks for your help 댓글 수: 0 ...
In this post, we’re going to cover how to plot XGBoost trees in R. XGBoost is a very popular machine learning algorithm, which is frequently used in Kaggle competitions and has many practical use cases. Let’s start by loading the packages we’ll need.
In lattice, there is a function called splom for the display of scatter plot matrices. For large datasets, the panel.hexbinplot from the hexbin package is a better option than the default panel. As an example, let’s use some meteorological data from MAP

Learn about factor analysis - a simple way to condense the data in many variables into a just a few variables.
Welcome to the RStudio Community Forum. This type of PCA plot uses the row names of the dataframe to label the plots. I cannot find any other way to specify them. In your case the row names are simply numbers from 1:nrow(aroma). So, try altering your dataframe like this before analys...
First, download the file and load it into your favorite text editor. Replace ss+ with t to create two tab delimited columns. I think this is probably easier than trying to get R to read data separated by at least 2 spaces, as the source file seems to be. Now, load your data into ...
That’s a really beautiful plot - aesthetically and also it’s good enough (or IMO better than a typical Pie Chart) in repesenting a realistic picture of the percentages. This ends this quick tutorial to make visualizations with waffle / square pie charts when dealing with percentags. Refere...
