myplots <- list()

y = seq(1,100,1)
for(i in 1:10) {
myplots[[i]] <- plot(x,y)
}
multiplot(plotlist = myplots, cols=2)
我收到以下错误:
单位出错(rep_len(1,nrow),“null”):'x'和'units'必须长度> 0另外:警告信息:矩阵(seq(1,cols * ceiling(numPlots / cols)) ,ncol = cols,nrow = ceiling(numPlots / cols)):数据长度超过矩阵的大小
您没有使用ggplot对象,您正在使用R基本图,因此多行不能正常工作:
你应该做这个:
library("ggplot2")
library("Rmisc")
myplots <- list()
x = seq(1,100,1)
y = seq(1,100,1)
df <- data.frame(x, y)
for(i in 1:10) {
myplots[[i]] <- ggplot(data=df, aes(x,y)) + geom_point()
}
multiplot(plotlist = myplots, cols=2)
?的multiplot:
Usage
multiplot(..., plotlist = NULL, cols = 1, layout = NULL)
Arguments
... ggplot objects
plotlist a list of ggplot objects
cols Number of columns in layout
layout A matrix specifying the layout. If present, 'cols' is ignored
