Legend function in R adds legend box to the plot. legend() function in R makes graph easier to read and interpret in better way. lets see an example on how to add legend to a plot with legend() function in R. Syntax of Legend function in R: legend(x, y = NULL, legend, fill =...
To summarize: You learned in this tutorial how to change the item text of a ggplot2 legend in the R programming language. Let me know in the comments, in case you have any further comments and/or questions.Subscribe to the Statistics Globe Newsletter Get regular updates on the latest ...
In the previous part of this article, I have shown you many differenttypes of plots. However, there are plenty of programming tricks for the modification of plots in general. In the following, you will find a list of tutorials that explain such general modifications of plots in R. ggplot2 ...
lines(back,col="RosyBrown",lty=3)#lty=3表示用点线连起来 legend函数,图例说明: 1 legend(12,400,c("forehead","forearm","back"),col=c("DarkTurquoise","DeepPink","RosyBrown"),text.col=c("DarkTurquoise","DeepPink","RosyBrown"),pch=c(15,16,17),lty=c(1,2,3))#12表示x轴坐标为12,400...
通过legend函数我们可以添加图例。 x <- seq(-pi, pi, len = 65) plot(x, sin(x), type = "l", ylim = c(-1.2, 1.8), col = 3, lty = 2) points(x, cos(x), pch = 3, col = 4) lines(x, tan(x), type = "b", lty = 1, pch = 4, col = 6) ...
最近新手接触 R 语言,在做一道练习的时候,利用plot()进行画折线图,在最后一步调用legend() 添加图例的时候,死活都没有产生出来。 直接贴出 脚本 library("quantmod") symbols=c('^VLIC','GE','KO','AAPL','MCD') getSymbols(symbols,src='yahoo',from="2012-02-01",to="2013-02-01") ...
isUnused = (prn > 32); group = categorical(isUnused,[false true],["Used in Positioning Solution" "Unused"]); Visualize the satellites and specify the categorical groups in the GroupData name-value argument. Specify the PRN as the label for each point. Show the legend. Get skyplot(satA...

常用低水平作图函数有points(),lines(),text(),abline(),polygon(),legend(),title()和axis()。 8.3.1 加点与线的函数 points(),其作用是在已有图上加点,lines(),其作用是在已有图上加线。 8.3.2 在点处加标记 函数text()的作用是在图上加标记,命令格式为: ...
