ggplot2 r tutorial

will only find R in the data Science environment, and on the one hand, Python is widely used in many fields as a common language. such as network development. This tends to favor ranking results in Python. And the result is some negative effect.When and how do I use r?R is primarily used when data analysis tasks require individual servers to calculate or analyze independently. Exploratory work is great, handy for almost any type of data analysis, and often provides you with the tools you need,

of its learning resources, such as online ggplot2 tutorials, Cheatsheet, and a teaching book written by Hadleywehan. The Ggvis package allows you to create interactive Web graphics using basic graphics syntax (see Tutorial). Do you know Hans Rosling Ted course? teach you how to use Googlevis (a Google chart interface) to reconstruct a chart. If you are having problems drawing data, this article will help you. You can see more visual resou

R Language Data Analysis series eight--by Comaple.zhangAgain on the polynomial regression, this section again mentions the polynomial regression analysis, understand the fitting phenomenon, and in-depth cross-validation (cross-validation), regularization (regularization) framework, to avoid the occurrence of overfitting phenomenon, From a more in-depth perspective, this paper explores the theoretical basis and how to bring ideals into reality based on R.Knowledge points in this section, and data

the y-axis. An increase in the second figure may indicate the elbow standard. Library (effects) library ( sjplot) Library (Ggplot2) sjc.elbow (Data,show.diff = FALSE) From the elbow value diagram below, you can see that the inflection point of the curve is approximately around 5: 2, use the Nbclust () function to verify the elbow value From the upper elbow value graph, you can see that the inflection point of the curve is 3, and you can also u

We know that both Java and Python have error handling mechanisms, and Java is a try ... In the form of catch, Python is try ... Except form, this kind of grasping the wrong form is very good, there are similar things in R, that is the Trycatch function, just beginning is not know, and then the R Machine learning actual combat that book code to write a time to know, specific see how to use the put:(1) Crawl errorTryCatch (Libray (XX), Error=function (e) {print ("error occurred")})Results:[1] "err

Turn http://www.cnblogs.com/jiangmiaomiao/p/6991632.html0 IntroductionR supports 4 types of graphics: base graphics, grid graphics, lattice graphics, Ggplot2. Where the Base graphics is the default graphics system for R.1 Basic graphics Functions plot ()The type parameter in the plot () command is used to clarify how the drawing is drawn, using the following type values: "P" for "points" "L" for "lines" "O" for "overlaid" (e.g., lines

machine Learning course), and the syntax of the R language is pretty good in formula settings.2. Furthermore, it is the corresponding Python library of the static graphics library Ggplot2 and the interactive graphics library D3. The Matplotlib library is not easy to install, it is difficult to use, and it is not easily built for interactive graphics for the web.3. The third is the scalability of the numpy and pandas libraries when dealing with large
