Identify (x, y, labels, ...)4.4 Three-dimensional graphicsThere are three basic functions for drawing three-dimensional graphs in R, respectively:Image (x, y, z), which produces a rectangular mesh that represents the z value in different colors.Contour (x, y, z), which is the value of a contour.PERSP (x, y, z) produces a 3D surface.4.5 Lattice PackageLattice a dataset drawing for multiple variables, most of w

Yesterday, a student who planned a city in South University asked me on Sina Weibo He converted JSON data into a vector image. I have never heard of this conversion before. I went to the website and checked it, the discovery of Chicago really put the city planning data on GitHub, see here: http://thechangelog.com/the-city-of-chicago-is-on-github/ Select one of them at will. Here I select bikeRoutes in Chicago, you can see the projects on GitHub, including data and examples. In readme.

While space, R language has some map methods. So stand on the shoulders of giants and draw a map today.Basic Map Method:1.

The two months have not written any code. Also did not do any big project, basically is to write in the previous project that uses the Ggplot2 visualization data to make some supplementary supplement, most technical difficulty all in Ggplot2 and the R language Excel processing here solves and summarizes.

In the R environment, different packages to draw maps is available. I lost the count by now; Surely, Spand Ggmap deserve consideration. Despite the great availability of R functions dedicated to this topic, in the past, when I needed to draw a very basic map of Italy with regions marked with different colours (namely a choropleth map), I had a bit of difficulties.My expectation is that building a choropleth map of Italy using R is a extremely trivial procedure, but my experience WA S different.

parameters, respectively, different groups are expressed in different color/dot form. The R language sample code (based on color grouping) is as follows:# Base functions: Colour set Group Ggplot (SAH, aes (x = ageyear, y = heightin, colour = Sex)) + # Scatter graph function geom_point ()Operation Result:The example code for the R language (based on the dot-form grouping) is as follows:# Base function: Shape set grouping Ggplot (SAH, aes (x = ageyear, y = heightin, shape = sex)) + # Scatter g

Qplot means quick plot, which is part of the GGPLOT2 package, which needs to be loaded before the package is used.Qplot Parameters:Qplot (x, y = NULL, ..., data, facets = NULL, margins = FALSE, geom = "Auto", Xlim = C (Na, NA), Ylim = C (Na, na), log = "", main = null, Xlab = Deparse (Substitute (x)), Ylab = Deparse (substitute (y)), ASP = NA, stat = null, Position = NULL)Where: X and y represent the x-axis and y-axisFacets for paging:

Big night, in Hefei study period a laboratory of QQ asked me an R language drawing problem, is asked to add value on the column chart, tried, and did not solve with R, but instead of using Excel, forcing lattice also do not reduce AH.

Today encountered an exception, the code is as follows:set.seed(12345)require(ggplot2)AData i p # all rightp p # Error: Aesthetics must either be length one, or the same length as the dataProblems:AData下面的代码就ok:example myplot geom_text(aes(label=rownames(example)), size=4.4, hjust=0.5, vjust=-1)根据异常信息，应该是说Glabel与AData的长度不同，但具体什么原因不了解。stackover上面的解释是：对于0.9.0版本的ggplot2有这个问题，0.9.1版本中已经解决。（http://stackoverflow.

Four graphics systems in the 16.1 RThe underlying graphics functions are automatically called, and the calls to the grid and lattice functions must be loaded with the appropriate packages (such as the Library (lattice)). To invoke the Ggplot2 function you need to download and install the package (Install.packages ("Ggplot2")) and load it before first use (library (GGPLO
