Labeling a curve in R using labcurve

Question

I'm getting back into working with R and I need to make a plot with numerous lines from three separate matrices. Currently, I'm using matplot and matlines to get the lines to plot. I want to label each line with its title centered horizontally and vertically on the line and I think there's a way to do it with labcurve. Unfortunately, I'm only finding the manual page for labcurve and no really clear examples of how to use it when I Google for it.

Can someone give me an example of using labcurve to place a label on a set of plotted lines produced similarly to how I described?

Thanks!

Answer 1

您可能会查看包 directlabels（用户 2011 年的海报价格），它比 labcurve 灵活得多，并且可以与 ggplot 和lattice 一起使用。

Answer 2

I ended up using thigmophobe.labels from the plotrix package. It works like this:

thigmophobe.labels(labelCoord.x,labelCoord.y,c("Title"),col="darkorange",font=2, cex=1)

where labelCoord gives the x and y location where you want your title text to go.
