R ggplot2瀑布问题

Question

嗨，我遇到了一个错误

Error: Discrete value supplied to continuous scale

当我在下面执行时。按照 https://www.jigsawacademy.com/waterfall-charts-using-ggplot2-in-r/.

上的简单 R 瀑布教程

想知道这是否过时了，我遗漏了一些简单的东西。

library(ggplot2)
library(dplyr)
balance <- data.frame(
  desc = c(
    "Starting Cash",
    "Sales",
    "Refunds",
    "Payouts",
    "Court Losses",
    "Court Wins",
    "Contracts",
    "End Cash"
  ),
  amount = c(2000, +3400, -1100, -100, -6600, 3800, 1400, 2800)
)
balance$desc <- factor(balance$desc, levels = balance$desc)
balance$id <- seq_along(balance$amount)
balance$type <- ifelse(balance$amount > 0, "in","out")
balance[balance$desc %in% c("Starting Cash", "End Cash"),+"type"] <-
  "net"
balance$end <- cumsum(balance$amount)
balance$end <- c(head(balance$end, -1), 0)
balance$start <- c(0, head(balance$end, -1))
balance <- balance[, c(3, 1, 4, 6, 5, 2)]

ggplot(balance, aes(desc, fill = type, x = desc)) + geom_rect(aes(
  xmin = id - 0.45,
  xmax = id + 0.45,
  ymin = end,
  ymax = start
))


Rstudio version 1.3.1073
R - version 4.0.2
ggplot2 - version 3.3.2

有什么想法吗？

谢谢

对您的代码稍作修改，我得到了这个：

library(ggplot2)
library(dplyr)
#Data
balance <- data.frame(
  desc = c(
    "Starting Cash",
    "Sales",
    "Refunds",
    "Payouts",
    "Court Losses",
    "Court Wins",
    "Contracts",
    "End Cash"
  ),
  amount = c(2000, +3400, -1100, -100, -6600, 3800, 1400, 2800),
  stringsAsFactors = F
)
balance$desc <- factor(balance$desc, levels = balance$desc)
balance$id <- seq_along(balance$amount)
balance$type <- ifelse(balance$amount > 0, "in","out")
balance[balance$desc %in% c("Starting Cash", "End Cash"),"type"] <- "net"
balance$end <- cumsum(balance$amount)
balance$end <- c(head(balance$end, -1), 0)
balance$start <- c(0, head(balance$end, -1))
balance <- balance[, c(3, 1, 4, 6, 5, 2)]
#Plot
ggplot(balance, aes(desc, fill = type)) + geom_rect(aes(
  x = desc,
  xmin = id - 0.45,
  xmax = id + 0.45,
  ymin = end,
  ymax = start
))

输出：

我按照您在问题中包含的网页中的说明进行操作。
