legend(x=q-70, y=m, bty = "n", 
  legend = c("1","2","3", "4","5", "6","7", "8","9", "10","11", "12","13", "14","15", "16","17", "18","19", "20"), 
  lty = c(1,1,1,1,1,1,1,1,2,2,2,2,2,2,2,2,4,4,4,4), 
  col = c("black", "red","green","blue","cyan","magenta","yellow","gray","black", "red","green","blue","cyan","magenta","yellow","gray","black", "red","green","blue"),  
  y.intersp=0.7, cex = 0.95,seg.len = 1.3, lwd = 2)

Answer 1

I notice that you have explicitly set y.intersp=0.7. I wonder if you have somehow set x.intersp as well. At any rate, if nothing else works for you, you could try various values of x.intersp until you get a position that you want. Here is a simple example on a blank background to show how x.intersp adjusts the position.

par(mfrow=c(1,2))
plot(0:2, pch="", xlab="", ylab="", bty="n", xaxt="n", yaxt="n", 
    main="x.intersp=1")
legend(x=1, y=2, bty = "n", 
  legend = c("1","2","3", "4","5","6","7","8","9","10",
    "11","12","13","14","15","16","17","18","19","20"), 
  lty = c(1,1,1,1,1,1,1,1,2,2,2,2,2,2,2,2,4,4,4,4), 
  col = c("black", "red","green","blue","cyan","magenta","yellow",
    "gray","black", "red","green","blue","cyan","magenta","yellow",
    "gray","black", "red","green","blue"),  
    x.intersp=1, y.intersp=0.7,  cex = 0.95,seg.len = 1.3, lwd = 2)

plot(0:2, pch="", xlab="", ylab="", bty="n", xaxt="n", yaxt="n", 
    main="x.intersp=4")
legend(x=1, y=2, bty = "n", 
  legend = c("1","2","3", "4","5","6","7","8","9","10",
    "11","12","13","14","15","16","17","18","19","20"), 
  lty = c(1,1,1,1,1,1,1,1,2,2,2,2,2,2,2,2,4,4,4,4), 
  col = c("black", "red","green","blue","cyan","magenta","yellow",
    "gray","black", "red","green","blue","cyan","magenta","yellow",
    "gray","black", "red","green","blue"),  
    x.intersp=4, y.intersp=0.7,  cex = 0.95,seg.len = 1.3, lwd = 2)
