我正在尝试使用带有默认参数的 sen2r() 函数（包 sen2r_1.3.2），但出现以下错误：

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

我知道错误要我填写一些参数，但源手册清楚地表明默认值应该可以工作，并且可以在启动 GUI 时随后设置参数。

使用 s2_gui() 启动闪亮的应用程序，但当我尝试“保存并关闭”时一直挂起

   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，是否可以请具有“较高声誉”的人创建一个 sen2r 标签，以便于后续通信？

这是追溯...

6: strsplit(paste(c(...), collapse = sep), "\n")

       log = log, globenv = sen2r_env, .only_list_names = FALSE)
1: sen2r()

我s2_gui()按原样运行...没有指定参数。但是我现在正在运行依赖项检查，我怀疑即使是 GUI 也应该可以解决问题。

此错误是由代码错误引起的，该错误已修复（请参阅GitHub 问题 292）。

在 sen2r CRAN 版本更新之前，bug 可能是：

  1. 解决了安装 sen2r GitHub 版本 ( remotes::install_github("ranghetti/sen2r"))，或
  2. check_gdal()在运行 sen2r() 之前绕过启动。

这是原始代码中的一个错误。

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，我将截断大部分字符串：

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

请注意它是如何以逗号和右括号结尾的？是的，这是 R 中的语法错误。（这已在原始回购中作为问题 292提交。）
