尝试根据 R 中的日期进行过滤，在 charToDate(x) 中收到错误：字符串不是标准的明确格式

Question

我正在尝试将我的数据框过滤为财政年度 (10-01-2018 / 09-31-2019) 内的日期。

原以为这样会更简单，但我一直收到错误消息。

Error in charToDate(x) : 
  character string is not in a standard unambiguous format

这是我正在尝试的：

数据集：

toStata <- structure(list(`Advance Identifier` = c("A00010001", "A00010001", 
"A00010001", "A00010001", "A00010001"), `Date Due` = structure(c(1312934400, 
1317772800, 1325721600, 1333584000, 1341446400), class = c("POSIXct", 
"POSIXt"), tzone = "UTC"), Disbursement = c(85740440.38, 0, 0, 
0, 0), `Principal Due` = c(0, 0, 0, 0, 0), `Interest Due` = c(0, 
425817.56, 699557.43, 691953.54, 691953.54), `Capitalized Interest Due` = c(0, 
0, 0, 0, 0), `Repayment Timing` = c("Beginning", "Beginning", 
"Beginning", "Beginning", "Beginning"), `Disbursement Timing` = c("Beginning", 
"Beginning", "Beginning", "Beginning", "Beginning"), `Capitalized Interest` = c(0, 
0, 0, 0, 0), Payment = c(0, 425817.56, 699557.43, 691953.54, 
691953.54), `Cash Grant Amount` = c(0, 0, 0, 0, 0), `Cash Grant Prepayment Effect Principal` = c(0, 
0, 0, 0, 0), `Cash Grant Prepayment Effect Interest` = c(0, 0, 
0, 0, 0), `Cash Grant Prepayment Effect Capitalized Interest` = c(0, 
0, 0, 0, 0), `Interest Rate` = c(0.03237, 0.03237, 0.03237, 0.03237, 
0.03237), `Payment Frequency` = c("Quarterly", "Quarterly", "Quarterly", 
"Quarterly", "Quarterly"), `Modification Principal` = c(NA_real_, 
NA_real_, NA_real_, NA_real_, NA_real_), `Modification Interest` = c(NA_real_, 
NA_real_, NA_real_, NA_real_, NA_real_), `Modification Capitalized Interest` = c(NA_real_, 
NA_real_, NA_real_, NA_real_, NA_real_)), row.names = c(NA, -5L
), class = c("tbl_df", "tbl", "data.frame"))

library(tidyverse)
file <- toStata %>% 
  filter('Date Due' >= as.Date("2010-10-01", format = "%Y-%m-%d") & 'Date Due' <= as.Date("2011-09-31", format = "%Y-%m-%d"))

也许我的细节太多了？不确定，不管我每次都收到错误；任何替代方案都会有所帮助！

9 月、4 月、6 月和 11 月共 30 天...检查您在 filter()

中的第二次约会

此外，如果变量名称中包含非法字符（如空格），则需要使用反引号。
