如何通过 gt 表按升序显示我的月份（一月、二月、三月）？

Question

我有下面的两块代码。在第一个块中，我试图让数据准备好显示在 gt 表中。我的目标是在第 1 列中按升序显示月份缩写（Jan、Feb、March 等）的表格。目前，每次我运行第二块代码来创建表格时，它都会对月份数据进行排序按字母顺序排列。我研究了 lubridate 包，混淆了“month.abb”和“month.name”函数，并且仍然按字母顺序输出月份。请参阅下面使用的包和下面的块。

library(tidyverse)
library(quantmod)
library(tidyquant)
library(xts)
library(rvest)
library(stringr)
library(forcats)
library(lubridate)
library(tidyr)
library(plotly)
library(purrr)
library(PerformanceAnalytics)
library(gt)
library(paletteer)
library(readr)
library(janitor)
library(scales)
library(lubridate)

获取并清理数据以输入 gt（块 1）

start <- as.Date("2020-01-01")
end <- as.Date("2020-11-30")
StockMonthlyReturns <- c("XLC", "XLC", "XLP", "XLE","XLF", "XLV", "XLI","XLB", "XLRE", "XLK", "XLU") %>%
  tq_get(get = "stock.prices", 
         from = start,
         to = end) %>%
  group_by(symbol) %>%
  tq_transmute(select = adjusted,
               mutate_fun = periodReturn,
               period = "monthly",
               col_rename = "StockMonthlyReturns")

stockdata <- StockMonthlyReturns %>% group_by(symbol, Month = floor_date(date, "month")) %>% summarise(Amount = sum(StockMonthlyReturns))
monthnum <- month(stockdata$Month)
stockdata <- cbind(stockdata, monthnum)
stockdata <- stockdata %>% rename(Month_Num = ...4)
stockdata$Month_Num <- month.abb[stockdata$Month_Num]
stockdata <- stockdata %>% 
  select(-Month)
stockdata <-  stockdata %>% rename(Month = "Month_Num")
#stockdata$Month <- months(as.Date(stockdata$Month))
stockdata <- adorn_rounding(stockdata, digits= 4) # Rounding Returns 
stockdata$Amount <- percent(stockdata$Amount, accuracy = 0.01) # Changing Decimals to Percent 

使用 dplyr 使用 gt (Chunk 2) 绘制数据图表

stockdata %>% 
  tidyr::spread(key="symbol", value = Amount) %>%
  gt(rowname_col = "Month") %>%
  tab_header(title = "Monthly Return of SPDR ETF's")

Answer 1

你可以尝试一下：

library(tidyverse)
library(gt)

stockdata %>% 
  mutate(Month = factor(Month, month.abb)) %>%
  tidyr::spread(key=symbol, value = Amount) %>%
  #tidyr::pivot_wider(names_from = symbol, values_from= Amount) %>%
  gt(rowname_col = "Month") %>%
  tab_header(title = "Monthly Return of SPDR ETF's")

另请注意，

spread

已被淘汰，取而代之的是

pivot_wider

。
