r软件包开发-自己的功能对于opencpu不可见 [英] r package development - own function not visible for opencpu

问题描述

我刚开始编写R包.

r软件包开发导入未加载建议我使用roxygen2. 我曾经叫devtools::document()并且生成了名称空间.

r package development imports not loaded advised me to use roxygen2. I once called devtools::document() and the namespace was generated.

但是，当我加载这个简单的程序包(或通过opencpu尝试)时，该功能不可用.

However when I load this simple package (or try it via opencpu) the functions are NOT available.

在本地R中调用代码似乎可行

calling the code in native R seems to work

test2::hello()
[1] "Hello, world!"

像这样启动opencpu:

Starting opencpu like:

1)通过library(opencpu)

2)执行opencpu$restart，它将显示端口号

2) execute opencpu$restartwhich will show a port number

3) http://localhost:myPortNumber/ocpu/library/myPackage/info --->此端点有效

3) http://localhost:myPortNumber/ocpu/library/myPackage/info ---> this endpoint works

如评论中所述，这不是调用函数的适当"方法.但是，如果通过HTTP作为http://public.opencpu.org/ocpu/library/stats/R/quantile/print调用函数，则opencpu默认为myfunction/print，即使当我调用hello函数时，该函数也不起作用.

As mentioned in the comments this is not a "proper" way of calling a function. However opencpu defaults to myfunction/print if a function is called via HTTP as http://public.opencpu.org/ocpu/library/stats/R/quantile/printand even that does not work when I call the hello function.

这是如何调用更复杂的函数的演示:

This is a demonstration of how to call a more complex function:

curl http://localhost:myPortNumber/ocpu/library/stats/R/quantile/json -d '{"type":1,"x":[1,2,3,4,5,6,7,8,9,10],"probs":[0.05,0.25,0.75,0.95]}' -H "Content-Type: application/json"

您可以简单地通过以下方式对其进行测试:

You can simply test it via:

curl http://public.opencpu.org/ocpu/library/stats/R/quantile/json -d \
'{"type":1,"x":[1,2,3,4,5,6,7,8,9,10],"probs":[0.05,0.25,0.75,0.95]}' \
-H "Content-Type: application/json"

我确实通过sudo安装了它，

I did install it via sudo like:

sudo R CMD INSTALL test2_0.1.tgz

意味着它应该在/library/test2端点中可以使用.

that means it should be available via in the /library/test2 endpoint.

它仍然是错误的API端点->我缺少R子目录

It still was the wrong API endpoint --> I was missing the R sub-directory

http://localhost:myPort/ocpu/library/myPackage/R/hello/

推荐答案

它仍然是错误的API端点->我缺少R子目录

It still was the wrong API endpoint --> I was missing the R sub-directory

http://localhost:myPort/ocpu/library/myPackage/R/hello/
