試圖找出在創建點時如何將點或數據序列添加到現有的格子面板。這是否與plot.points和/或更新功能有關?在格子面板中合併或重疊xyplots
# Initialize first plot
library(lattice)
a <- xyplot(Sepal.Length~Sepal.Width, groups=Species, data=iris
, subset=Species %in% levels(Species)[1:2])
print(a)
# Create second plot to overlay or merge with the first plot
b <- xyplot(Sepal.Length~Sepal.Width, groups=Species, data=iris
, subset=Species %in% levels(Species)[3])
# Initial attempt at merging plots:
library(latticeExtra)
print(c(a,b)) # this displays the data in an adjacent second panel
print(c(a,b,layout=c(1,1))) # and this only shows series "b"
注:在本例中,兩條曲線「A」和「B」來自原始虹膜數據幀,但理想的解決方案將具有鮮明的dataframes工作。
任何想法? 謝謝!

+1!你應該提到使用'latticeExtra'軟件包。 – agstudy
