我正在使用 forestplot 包在 r 中制作森林图(请参阅https://cran.r-project.org/web/packages/forestplot/forestplot.pdf)。
我对情节的外观感到满意,但问题是分辨率不够高。我尝试了各种方法来增加绘图的大小,但无论我做什么,总绘图区域始终保持不变(即使我可以更改文本的大小等)。
我包括几个数字来说明我的观点。第二个简单地通过将 tiff 函数的宽度和高度参数设置为第一个图形的两倍来创建。通常,这会导致绘图在整个区域上拉伸,但这里似乎并非如此,而是第二张图像仅获得宽的白色边距。
代码如下:
library(rmeta)
tiff("/mypath", width=480*multifactor, height = 480*multifactor)
forestplot(tabletext,m,l,u,zero=0,is.summary=c(TRUE,FALSE,TRUE,rep(FALSE,(nrow(input)+1)),TRUE,TRUE,TRUE),clip=c(log(0.5),log(32)), xlog=TRUE,xlab="RR",xticks=c(0.5,1,2,4,8,16,32),col=meta.colors(box="royalblue",line="darkblue", summary="royalblue"))
dev.off()
这是(有点混乱)可重现的例子:
tabletext <-
