我正在 baseR 中绘制多个图形，并且我试图在图形的右下角绘制一个文本.我尝试使用 mtext() 但这并没有给我想要的结果.你会怎么做?最终的想法是生成如下图所示的内容.我怎么能这样做?

I am plotting multiple graphs in baseR and I am trying to plot a text in the lower rightern corner of my plots. I tried using mtext() but this doesn't give me the desired result. How would you do this? The idea in the end is to generate something like the graphic below. How could I do this?

这是我用来生成绘图的代码.

Here is my code I use to generate the plots.

xy <- data.frame(NAME=c("NAME1", "NAME1","NAME1","NAME1","NAME2","NAME2","NAME2"),ID=c(47,47,47,47,259,259,259),YEAR=c(1932,1942,1965,1989,2007,2008,2014),VALUE=c(0,NA,-6,-16,0,-9,-28), test=c("text1","text1","text1","text1","text2","text2","text2")) # split data by index ind <- split(x = xy,f = xy[,'ID']) plot1 <- function(x) { fname <- paste0(x[1, 'ID'], '.png') png(fname, width=1679, height=1165, res=150) par(mar=c(6,8,6,5)) plot(x = c(1946, 2014), y = range(x$VALUE, na.rm=TRUE), type='n', main=x[1, 'NAME'], xlab="Time [Years]", ylab="Value [m]") axis(2, at = seq(-100000, 100000, 100), cex.axis=1, labels=FALSE, tcl=-0.3) points(x[,c('YEAR','VALUE')], type="l", lwd=2) points(x[,c('YEAR','VALUE')], type="p", lwd=1, cex=0.5, pch=21, bg='white') abline(h=0) mtext(x$test, side=1, ) dev.off() } plot2 <- function(x) { fname <- paste0(x[1, 'ID'], '.png') png(fname, width=1679, height=1165, res=150) par(mar=c(6,8,6,5)) plot(x[,c('YEAR','VALUE')], type='n', main=x[1, 'NAME'], xlab="Time [Years]", ylab="value [m]") axis(2, at = seq(-100000, 100000, 100), cex.axis=1, labels=FALSE, tcl=-0.3) points(x[,c('YEAR','VALUE')], type="l", lwd=2) points(x[,c('YEAR','VALUE')], type="p", lwd=1, cex=0.5, pch=21, bg='white') abline(h=0) mtext(x$test, side=1) dev.off() } lapply(ind, function(x) ifelse(any(x$YEAR < 1946 & x$YEAR < 2014), plot2(x), plot1(x)))

推荐答案

plot(1) title(sub="hallo", adj=1, line=3, font=2)
