我正在尝试制作一个由多个图组成的图。这些图是在循环内用ggplot（库（“ggplot2”））制作的，并保存到两个列表中。第一个列表的图表应该位于多个图的左侧，第二个列表的图表是右侧的图。 一般来说，我让它适用于其他六个地块，每个地块分别制作（plot1，...，plot6）。
string formatter(string url) => $"URL: {url}";
...
var googleUrl = "http://google.com";
...
var log = formatter(googleUrl);
和
一样好用multiplot(p1,p2,p3,p4,p5,p6,cols=2)
但是当我想对循环内的图进行多重绘图时，之后的多重图不起作用。请看下面的一些代码......
plotlista <- list(p1,p2,p3)
plotlistb <- list(p4,p5,p6)
multiplot(c(plotlista,plotlistb),cols=2)
发生以下错误：
错误：美学必须是长度1或与长度相同 dataProblems：名称（AAA）
循环中有13次运行，但即使我将运行切换为2，也会发生相同的错误。
循环内的以下几行也适用于每次运行并正确保存了jpeg。
plotlist1 <- list()
plotlist2 <- list()
for(a in types){
... some data handling ...
p5 <- ggplot(df.1, aes(xmin = wm, xmax = w, ymin = 0, ymax = height, fill = names(aaa))) +
geom_rect(color="darkgrey")+ geom_text(aes(x = (wm+w)/2, y = 150 , label = names(aaa), size=16, angle=90)) +
theme_bw() + labs(x = "cummulated", y = "costs") +
theme(axis.ticks = element_blank(), legend.position = "none") + ylim(-150, 400) + xlim(-150, 1000) +
scale_fill_manual(values=aaa) +
ggtitle(paste("type ",a,sep="- ") ) + theme(plot.title = element_text(lineheight=.8, face="bold"))
plotlist1[[which(types==a)]] <- p5
... some data handling ...
p55 <- ggplot(df.1, aes(xmin = wm, xmax = w, ymin = 0, ymax = height, fill = names(aaa))) +
geom_rect(color="darkgrey")+ geom_text(aes(x = (wm+w)/2, y = 150 , label = names(aaa), size=16, angle=90)) +
theme_bw() + labs(x = "cummulated", y = "costs") +
theme(axis.ticks = element_blank(), legend.position = "none") + ylim(-150, 400) + xlim(-150, 1000) +
scale_fill_manual(values=aaa) +
ggtitle(paste("type ",a,sep="- ") ) + theme(plot.title = element_text(lineheight=.8, face="bold"))
plotlist2[[which(types==a)]] <- p55
filepath <- paste("byxxxx",Agglevel,a,".jpg",sep="")
jpeg(filename = filepath , width = 750, height = 750)
multiplot(plotlist=list(p5,p55),cols=2)
dev.off()
}
multiplot(plotlist=c(plotlist1,plotlist2),cols=2)
也可以对最后一次循环中使用的filepath <- paste("byxxxx",Agglevel,a,".jpg",sep="")
jpeg(filename = filepath , width = 750, height = 750)
multiplot(plotlist=list(p5,p55),cols=2)
dev.off()
和p5以及p55和listplot1[[13]]进行多重绘图：
listplot2[[13]]多值函数来自http://www.cookbook-r.com/Graphs/Multiple_graphs_on_one_page_%28ggplot2%29/：
multiplot(plotlist=list(p5,p55),cols=2)
multiplot(plotlist=c(plotlist1[13],plotlist2[13]),cols=2)
在循环中保存ggplot对象是否有问题？
添加可重现的示例：
# 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.
#
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))
}
}
}
错误：手动刻度值不足。需要25但只有4 提供。
答案 0 :(得分：0)
现在它正在运作......谢谢@Heroka
