Hello,
I have a simple question that I could not really figure out. I am plotting
labels within a graph using the text function. I first plot the first label by
specifying the x and y coordinates on the graph. Then to plot the second label
next to it, I am using te strwidth function to get the width of the previous
label in user coordinate then add the maximum width to the x value. However,
this is not working:
Here is an example:
lab1<-c("Hocine& Ruba 2000", "Yasmine 2004","Ziad was born in 2006")
lab2<-c(20,22,45)
lab3<-c(54677,10900,200)
plot(-10:5,1:6)
text(par("usr")[1],2:4,lab1,adj=c(0,0.5))
text(par("usr")[1]+max(strwidth(lab1)),2:4,lab1,adj=c(0,0.5))
However, this is not working OK. I would like to get the max width of lab1 as
it appears in the figure then add that amount to plot lab2 and so forth. I
would like to leave only one blank column between successive labels.
Does this give you what you have in mind:
text(par("usr")[1] + max(strwidth(paste(lab1, ""))),
2:4,lab1,adj=c(0,0.5))
