You could do something like this:
mydata=c(1,2,1,1,6,7,-1,-1,5,-1)
color= as.numeric(mydata== -1) +1
plot(mydata,col=color)
This will give you a plot where the -1's are in red (color = 2) and the
other numbers in black (color=1).

Hi. I am plotting graphs for values ranging
Try:
x <- c(1,2,1,1,6,7,-1,-1,5,-1)
plot(x, col = ifelse(x == -1, "red", "black"), pch = 16)

Hi. I am plotting graphs for values ranging between -1 and 10, for example:
(1,2,1,1,6,7,-1,-1,5,-1)
I am trying to plot the graphs so that the points with value of -1 will be
in one specific color, and the rest of the points will be in one different
specific color. I would be grateful for any ide
