我有一个情节,我需要调整连续的传奇。我该怎么做?如何在R中调整图例中的图例?

plot(x,y) 
legend(c("x","y")) 

我需要的传说应该是在一行

----- x     --------- y

你想设置horiz=TRUElegend。以下是默认行为(horiz=FALSE)与horiz=TRUE的比较。

enter image description here

此图是根据the second example from the legend documentation

layout(matrix(1:2,nrow=1)) 
# `horiz=FALSE` (default behavior) 
plot(x, sin(x), type = "l", ylim = c(-1.2, 1.8), col = 3, lty = 2, main="horiz=FALSE (Default)") 
points(x, cos(x), pch = 3, col = 4) 
lines(x, tan(x), type = "b", lty = 1, pch = 4, col = 6) 
legend(-1, 1.9, c("sin", "cos", "tan"), col = c(3, 4, 6), 
     text.col = "green4", lty = c(2, -1, 1), pch = c(NA, 3, 4), 
     merge = TRUE, bg = "gray90") 
# `horiz=TRUE` 
plot(x, sin(x), type = "l", ylim = c(-1.2, 1.8), col = 3, lty = 2, main="horiz=TRUE") 
points(x, cos(x), pch = 3, col = 4) 
lines(x, tan(x), type = "b", lty = 1, pch = 4, col = 6) 
legend(-1, 1.9, c("sin", "cos", "tan"), col = c(3, 4, 6), 
     text.col = "green4", lty = c(2, -1, 1), pch = c(NA, 3, 4), 
     merge = TRUE, bg = "gray90", horiz=TRUE)
