R中的图形段

Question

我想在 R 中绘制分段数据。也就是说，我有以下形式的数据

| Product               | Date   | Origination | Rate | Num | Balance   |
|-----------------------|--------|-------------|------|-----|-----------|
| DEMAND DEPOSITS       | 200505 | 198209      | 0    | 1   | 2586.25   |

| DEMAND DEPOSITS       | 200505 | 198410      | 0    | 1   | 44555.23  |

我想在 Y 轴上按“余额”为每个“产品”类型绘制一条线。在 X 轴上，我想放置“起源”。理想情况下，我还想设置颜色来区分线条。数据当前不在 data.frame 形式中，所以如果我需要改回该形式，请告诉我。

尽管我确定有，但我无法在网上找到信息丰富的解决方案。

谢谢，

Answer 1

正如@zx8754 提到的，您应该提供可重现的数据。 在没有测试代码的情况下（因为没有可重现的数据），我建议如下，假设数据在 data.frame 'data' 中：

all_products <- unique(data$Product)
colors_use <- rainbow(length(all_products))

plot(y = data[data$Product == all_products[1],"Balance"],
    x = data[data$Product == all_products[1],"Origination"],
    type = "l",
    col = colors_use[1],
    ylim = c(min(data$Balance, na.rm = T),max(data$Balance, na.rm = T)),
    xlim = c(min(data$Origination, na.rm = T),max(data$Origination, na.rm = T)))

for(i_product in 2:length(all_products)){
    lines(y = data[data$Product == all_products[i_product],"Balance"],
        x = data[data$Product == all_products[i_product],"Origination"],
        col = colors_use[i_product])
}

Answer 2

我没有足够的声誉来发表评论，所以我写它作为答案。为了使@tobiasegli_te 的答案更短，第一个plot 可以是plot(Balance~Origination,data=data,type='n')，然后为i_product in 1:length(all_products) 完成后续lines。这样你就不用担心ylim。这是使用 Grunfeld 数据的示例。

z <- read.csv('http://statmath.wu-wien.ac.at/~zeileis/grunfeld/Grunfeld.csv')
plot(invest~year,data=z,type='n')
for (i in unique(as.numeric(z$firm))) lines(invest~year,data=z,
    subset=as.numeric(z$firm)==i, col=i)

另请注意，您的Origination 的间距不相等。您需要将其更改为 Date 或类似名称。

Answer 3

我猜你想要类似下面的东西：

df <- as.data.frame(df[c('Product', 'Balance', 'Origination')])
head(df)

Product  Balance Origination
1  DEMAND DEPOSITS         2586.25      198209
2  DEMAND DEPOSITS         3557.73      198304
3  DEMAND DEPOSITS        14923.72      198308
4  DEMAND DEPOSITS         4431.67      198401
5  DEMAND DEPOSITS        44555.23      198410
6  MONEY MARKET ACCOUNTS  65710.01      198209

library(ggplot2)
library(scales)
ggplot(df, aes(Origination, Balance, group=Product, col=Product)) + 
         geom_line(lwd=1.2) + scale_y_continuous(labels = comma) 

Answer 4

我不确定你想要什么，那是你想要的吗？

假设您将数据放在 data.txt 中，删除管道并将名称中的空格替换为“_”

d = read.table("data.txt", header=T)

prod.col = c("red", "blue", "green", "black" )
prod = unique(d$Product)

par(mai = c(0.8, 1.8, 0.8, 0.8))
plot(1, yaxt = 'n', type = "n", axes = TRUE, xlab = "Origination", ylab = "", xlim = c(min(d$Origination), max(d$Origination)), ylim=c(0, nrow(d)+5) )
axis(2, at=seq(1:nrow(d)), labels=d$Product, las = 2, cex.axis=0.5)
mtext(side=2, line=7, "Products")

for( i in 1:nrow(d) ){
myProd = d$Product[i]
myCol = prod.col[which(prod == myProd)]
myOrig  = d$Origination[i]
segments( x0 = 0, x1 = myOrig, y0 = i, y1 = i, col = myCol, lwd = 5 )
}
legend( "topright", col=prod.col, legend=prod, cex=0.3, lty=c(1,1), bg="white" )
