necessary tools to quickly start and run a large number of almost any type of data analysis. R can even be part of a big data solution. When you start using R, it's a good idea to first install the Rstudio IDE. After that, we recommend that you look at the following popular packages: Dplyr, Plyr and data.table can easily operate the package stringr Action String Zoo do regular and irregular time series work Ggvis, Lattice, and ggplot2 for data visual

Keynote and Tex, you can store graphics in separate files, "Slide.key" may look like a folder, but it is actually a directory.Robbins (2006) is a basic guide to drawing. The Ggplot2 package (wickham,2009) in R provides a beautiful, well-pivoted graphical default color.The power of the poster Pay attention to the layout and image coherence of the poster.

Plyr. Step 4: Learn specific packages in r–data.table and DplyrThis is the WHERE fun begins! Here are a brief introduction to various libraries. Let ' s start practicing some common operations. Practice the Data.table tutorial thoroughly here. Print and study the cheat sheet for data.table Next, you can has a look at the Dplyr tutorial here. For text mining, start with creating a word cloud in R and then learn learn through this series of Tutorial:part 1 and Pa RT 2. For so

The R language draws maps, which are often used in data analysis and can achieve very good results, and this section provides examples of how to use the R language tools to draw the ideal map.Examples of this section run smoothly under the R version 2.15.3 release, and other versions are pending.The code is as follows: The first small example# load the appropriate package, read the data, and then draw. Library (maptools), library (Ggplot2), China_map

the syntax is a little tricky, and matplotlib is not required at all. Just forget ggplot. compared with the GGPLOT2 in the R language, it seems that two packages are used and the likelihood is developed by the same person! The original author also said on GITHUB that the PYTHON library will no longer be updated! However, ggplot2 is really a drawing artifact, which is almost the only reason I am still usin

a lot of packages and testing available at any time, and can provide the necessary tools to quickly start and run a large number of data analysis of almost any type. R can even be part of a big data solution. When you start to use R, it is best to install RStudio IDE first. We recommend that you check the following popular packages: • Dplyr, plyr, and data. table can be operated easily • Stringr operator string • zoo performs regular and irregular time series operations • Ggvis, lattice, and

Currently, ggplot2 is mainly used for data visualization analysis. However, ggplot2 does not support 3D plotting, so you need to find other alternatives. The two alternatives found below are good, and the test is feasible, which is recorded here. Interactive 3D Library (RGL) with (mtcars, {plot3d (wt, DISP, mpg, Col="Red", Size = 3)}) Static 3D Library (scatterplot3d) with (mtcars, {scatterplot3d

1. Introduction to the three major mapping systems of R1.1 Basic drawing System (base plotting systems)-Artist's palette: drawing suitable for blank canvas· need to implement plans; visualize the logic of drawing and analyzing data in real time-Two steps = figure + Modify/Add = Perform a series of functions-Suitable for drawing 2D graphs1.2 Lattice Drawing System (Lattice plotting systems)-draw = Use a function call once (a graph)-Ideal for interacting with observational variables: How variable

Dynamic installation library in R languageIn an R script, we used some libraries, but found that the operating environment does not have the library, if you can detect if there is no this package, do not automatically install that much better. and R is very convenient to support these, as long as the Internet.The code is as follows:site"http://cran.r-project.org"if (!require("ggplot2")) { install.package("ggplot2
