Ggplot2 shows a small example of some data in the figure
Sometimes when we are drawing, we only want to show some contents. Of course, there is a corresponding syntax in ggplot2, but wouldn’t it be better if there is an R package to complete this work,gghighlightThe appearance of package solves this problem very well. Thank youHiroaki YutaniDevelop such an easytouse R package Let’s introduce how […]

R language classification regression decision tree interactive pruning and more beautiful visual analysis of cell image segmentation data set
Original link:http://tecdat.cn/?p=24956 The rpart () function of the basic method of drawing a classification or regression tree simply calls plot. Overall, however, the results were not beautiful. It turns out that there has been a better way to draw rpart () trees for some time. We can briefly browse how to implement it and further […]

Explore other layers of ggplot2
Ggplot2 package comes with many layers, which can basically meet our various drawing needs, but sometimes we need to draw some “weird” drawings, so we need to use some ggplot2 expansion packages. This article will introduce some useful ggplot2 expansion packages. Load R package library(tidyverse) # install.packages(‘wesanderson’) library(wesanderson) The wesanderson bag offers a lot of […]

Ggplot batch drawing
The scatter diagram and box diagram drawn by ggplot are very beautiful, which can be seen in many SCI papers. However, when it comes to multivariable big data, it is inefficient to input r code line by line to draw one by one. This article will introduce how to use ggplot to batch draw graphics. […]
