存在着一個不錯的功能的multiplot,這是我在總是被載入我自己的標準庫。它可以用google搜索,但是在這裏。

# Multiple plot function 
# 
# ggplot objects can be passed in ..., or to plotlist (as a list of ggplot objects) 
# - cols: Number of columns in layout 
# - layout: A matrix specifying the layout. If present, 'cols' is ignored. 
# 
# If the layout is something like matrix(c(1,2,3,3), nrow=2, byrow=TRUE), 
# then plot 1 will go in the upper left, 2 will go in the upper right, and 
# 3 will go all the way across the bottom. 
# 
library(ggplot2) 
multiplot <- function(..., plotlist=NULL, file, cols=1, layout=NULL) { 
    library(grid) 

    # Make a list from the ... arguments and plotlist 
    plots <- c(list(...), plotlist) 

    numPlots = length(plots) 

    # If layout is NULL, then use 'cols' to determine layout 
    if (is.null(layout)) { 
    # Make the panel 
    # ncol: Number of columns of plots 
    # nrow: Number of rows needed, calculated from # of cols 
    layout <- matrix(seq(1, cols * ceiling(numPlots/cols)), 
        ncol = cols, nrow = ceiling(numPlots/cols)) 
    } 

    if (numPlots==1) { 
    print(plots[[1]]) 

    } else { 
    # Set up the page 
    grid.newpage() 
    pushViewport(viewport(layout = grid.layout(nrow(layout), ncol(layout)))) 

    # Make each plot, in the correct location 
    for (i in 1:numPlots) { 
     # Get the i,j matrix positions of the regions that contain this subplot 
     matchidx <- as.data.frame(which(layout == i, arr.ind = TRUE)) 

     print(plots[[i]], vp = viewport(layout.pos.row = matchidx$row, 
             layout.pos.col = matchidx$col)) 
    } 
    } 
}

我用的是包grid.Extra

您沒有提供樣本數據,但如果你有4個地塊保存爲「A」,「B」,「C中的函數grid.arrange 「和‘d’,你的代碼將如下所示:

 grid.arrange(a, b, c, d, nrow=2, ncol=2) 

您可以使用‘?grid.arrange’來了解更多關於增加額外的東西進入你的情節,如標題,圖像的高度,等等。

 grid.arrange(a, b, c, d, nrow=4), top="YourTitleHere", heights=c(3,1,3,1))
