I did not know about matplot, but it did the work. using lines is my
default procedure but it can be time-consuming. Thank you all.

Hello,
Base R:
colrs <- rainbow(length(unique(ROI$Z)))
roi_wide <- reshape(ROI, v.names = "Y", timevar = "Z", idvar = "X",
direction = "wide")
matplot(roi_wide, type = "l", lwd = 3, lty = "solid", col = colrs)
Hope this helps,

No. I was wrong. ?plot.default says only one line color (the first) will be
used. So it appears that you need to use lines().

1. lines() *is* base R.
2. See the col argument of ?plot.default.

Hello
is it possible to color the data of a dataframe according to the
values of one column?
I have a dataframe that OI have subdivided into X and Y, with a third
Z with the sample number. I would like to plot Y~X but coloring using
Z. But I would like to use base R and not lines.
Is that possible?
