Question

我刚刚在Rstudio中完成了一个交易策略，我计划将其部署在ShinyApps.io上。这有一个问题。

首先，总会有一条警告信息：

Warning messages:
1: In getFromNamespace("checkEncoding", "shiny")(file) :
  The file "F:\newFinal/server.R" is not encoded in UTF-8. Please convert its encoding to UTF-8 (e.g. use the menu `File -> Save with Encoding` in RStudio). See http://shiny.rstudio.com/articles/unicode.html for more info. Falling back to the encoding "native.enc".
2: In getFromNamespace("checkEncoding", "shiny")(file) :
  The file "F:\newFinal/server.R" is not encoded in UTF-8. Please convert its encoding to UTF-8 (e.g. use the menu `File -> Save with Encoding` in RStudio). See http://shiny.rstudio.com/articles/unicode.html for more info. Falling back to the encoding "native.enc".

即使我使用UTF-8编码保存文件，每次部署应用程序时它仍会显示警告。

另一件事是我无法在ShinyApps中获取其他文件，如下所示：

source("helpers.R")
#source("loadfunction.R")
source("main2.R")
#source("main.R")
source("plotperiod.R")

以下日志显示系统找不到“getSymbols”函数。

Answer 1

不确定这是否可以解决问题但是为了获取文件，您需要添加local参数并将其设置为TRUE，如下所示：

source("helpers.R", local=TRUE)
source("main2.R", local=TRUE)
source("plotperiod.R", local=TRUE)

找不到功能＆＃34; getSymbols＆＃34;使用ShinyApps.io时
