我试图在for循环内绘制15条曲线到同一个图形上。理想情况下，我希望能够轻松区分它们。我也试过lines(dat[[i]], type = "l", col = rainbow(i))，但那不是运气。我只想要一个有15条曲线的情节，每条曲线都有自己独特的色彩。R：使用for循环绘制独特的线条

'COLS < - 彩虹（15）;行（dat [[i]]，type =“l”，col = cols [i]） –

@MattTyers谢谢。这工作很好。还有一种方法可以为此添加彩色编码图例吗？ – Adrian

你的名单长度是否一样？如果是这样，那么'matplot（data.frame（dat），col = rainbow（length（dat）），type =“l”，lty = 1）' – thelatemail

这与rainbow()，再加上一个图例..

par(mfrow = c(1, 1)) 
plot(NA, ylim = c(0, 7), xlim = c(0, 20)) 

cols <- rainbow(15) 
# cols <- heat.colors(15) 
# cols <- terrain.colors(15) 
# cols <- cm.colors(15) 

# I like a darker rainbow 
# darkerizer <- function(colors, dark=.85) adjustcolor(colors, red.f=dark, green.f=dark, blue.f=dark) 
# cols <- darkerizer(rainbow(15), dark=.85) 

for(i in 1:15) lines(dat[[i]], col = cols[i], lwd=2) 
legend("topleft", legend=paste("number",1:15), lwd=2, col=cols)

这里是ggplot2

library(ggplot2) 

# reformat the data 
data_long = data.frame(x = numeric(), y = numeric(), curve = character()) 
for(i in 1:length(dat)){ 
    y = dat[i][[1]] 
    x = 1:length(y) 
    data_long = rbind(data_long, data.frame(x, y, curve = i)) 
} 
data_long$curve = factor(data_long$curve) 

# create plot 
ggplot(data_long, aes(x, y, color = curve)) +geom_line() + theme_bw()

的解决方案你可以试试这个：

par(mfrow = c(1, 1)) 
plot(NA, ylim = c(1, 4), xlim = c(0, 10)) #better view over the lines 

mypal <- colorRampPalette(c("red", "green", "blue"))(15) 

for(i in 1:15){ 
     lines(dat[[i]], type = "l", col = mypal[i], , lwd=1.5) #thickness set to be higher 
       }

这将绘制：
