用R绘制交互式3D图
1. 安装rgl包、evd包和MASS包:
> install.packages("rgl") Installing package(s) into ‘D:/program/R/library’ (as ‘lib’ is unspecified) 试开URL’http://cran.dataguru.cn/bin/windows/contrib/2.15/rgl_0.92.892.zip' Content type 'application/zip' length 1937097 bytes (1.8 Mb) 打开了URL downloaded 1.8 Mb package ‘rgl’ successfully unpacked and MD5 sums checked The downloaded binary packages are in C:\Users\LiQiang\AppData\Local\Temp\RtmpIjwxP2\downloaded_packages > install.packages("evd") Installing package(s) into ‘D:/program/R/library’ (as ‘lib’ is unspecified) 试开URL’http://cran.dataguru.cn/bin/windows/contrib/2.15/evd_2.3-0.zip' Content type 'application/zip' length 1176009 bytes (1.1 Mb) 打开了URL downloaded 1.1 Mb package ‘evd’ successfully unpacked and MD5 sums checked The downloaded binary packages are in C:\Users\LiQiang\AppData\Local\Temp\RtmpIjwxP2\downloaded_packages > install.packages("MASS") Installing package(s) into ‘D:/program/R/library’ (as ‘lib’ is unspecified) 试开URL’http://cran.dataguru.cn/bin/windows/contrib/2.15/MASS_7.3-21.zip' Content type 'application/zip' length 872270 bytes (851 Kb) 打开了URL downloaded 851 Kb package ‘MASS’ successfully unpacked and MD5 sums checked The downloaded binary packages are in C:\Users\LiQiang\AppData\Local\Temp\RtmpIjwxP2\downloaded_packages
2. 输入程序
library(rgl) library(MASS) library(evd); data(lossalae) U=rand(lossalae[,1]+rnorm(nrow(lossalae),mean=0,sd=.001))/(nrow(lossalae)+1) V=rank(lossalae[,2])/(nrow(lossalae)+1) M=kde2d(qnorm(U), qnorm(V), n=35) persp3d(M$x, M$y, M$z, col='green',xlab="loss", ylab="alae", zlab="")
3. 输出3D图
