我正在绘制baseR中的多个图形,我试图在我的图形的下部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？
xy <- data.frame(NAME=c("NAME1","NAME1","NAME2","NAME2"),ID=c(47,47,259,259),YEAR=c(1932,1942,1965,1989,2007,2008,2014),VALUE=c(0,NA,-6,-16,-9,-28),test=c("text1","text1","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,y = range(x$VALUE,na.rm=TRUE),type='n',main=x[1,'NAME'],xlab="Time [Years]",ylab="Value [m]")
axis(2,at = seq(-100000,100000,100),cex.axis=1,labels=FALSE,tcl=-0.3)
points(x[,c('YEAR','VALUE')],type="l",lwd=2)
points(x[,type="p",lwd=1,cex=0.5,pch=21,bg='white')
abline(h=0)
mtext(x$test,side=1,)
dev.off()
}
plot2 <- function(x) {
fname <- paste0(x[1,res=150)
par(mar=c(6,5))
plot(x[,ylab="value [m]")
axis(2,side=1)
dev.off()
}
lapply(ind,function(x) ifelse(any(x$YEAR < 1946 & x$YEAR < 2014),plot2(x),plot1(x)))
解决方法
plot(1) title(sub="hallo",adj=1,line=3,font=2)
