無法使 sen2r 函數工作，缺少一些參數？

Question

我試圖使用帶有默認參數的 sen2r() 函數（包 sen2r_1.3.2），但收到以下錯誤：

Error in paste(c(...), collapse = sep) : argument is missing, with no default.

我知道錯誤要我填寫一些參數，但是源手冊明確說默認應該可以工作，並且可以在啟動GUI時隨后設置參數。

使用 s2_gui() 啟動閃亮的應用程序，但在我嘗試“保存並關閉”時一直掛起

   R version 3.6.3 (2020-02-29)
   Platform: x86_64-pc-linux-gnu (64-bit)
   Running under: Ubuntu 18.04.4 LTS

另外，有“較高聲譽”的人可以創建一個 sen2r 標簽，以便於后續通信嗎？

這是回溯...

我按s2_gui()運行s2_gui() ...沒有指定參數。 但是我現在正在運行依賴項檢查，我懷疑即使對於 GUI 也應該清除問題。

此錯誤是由代碼錯誤引起的，已修復（請參閱GitHub 問題 292 ）。

在 sen2r CRAN 版本更新之前，bug 可能是：

1. 解決了安裝 sen2r GitHub 版本（ remotes::install_github("ranghetti/sen2r") ），或
2. 在運行 sen2r() 之前繞過了啟動check_gdal() ()。

Answer 2

這是原始代碼中的一個錯誤。

在您提供的回溯中，它包括：

3: print_message(type = "waiting", "It seems you are running this package for the first time. ", 
       "Do you want to verify/install the required dependencies using a GUI (otherwise, an\n        automatic check will be performed)? (y/n) ", 
       )

值得注意的是，我將截斷大部分字符串：

3: print_message(type = "waiting", "It seems ... time. ", 
       "Do you ... performed)? (y/n) ",  
       )                         #    ^-- extra comma, invalid R syntax

注意它是如何以逗號和右括號結尾的？ 是的，這是 R 中的語法錯誤。（這已在原始存儲庫中作為問題 292提交。）
