R socketConnection-连接未打开，无法读取

我正在尝试调用

socketConnection

上的

load（）

函数。当我建立连接（在两个R进程之间）时，我检查套接字信息，我看到：

> s <- socketConnection(host = "localhost", 12345, server = FALSE, blocking=TRUE, open = "rb")
> s
        description               class                mode                text
"->localhost:12345"          "sockconn"                "rb"            "binary"
             opened            can read           can write
           "opened"               "yes"               "yes"

> s
        description               class                mode                text
"->localhost:12345"          "sockconn"                "rb"            "binary"
             opened            can read           can write
           "opened"               "yes"               "yes"
> z <- gzcon(s)
> z
               description                      class
"gzcon(->localhost:12345)"                    "gzcon"
                      mode                       text
                      "rb"                   "binary"
                    opened                   can read
                  "opened"                       "no"
                 can write
                     "yes"
> s
               description                      class
"gzcon(->localhost:12345)"                    "gzcon"
                      mode                       text
                      "rb"                   "binary"
                    opened                   can read
                  "opened"                       "no"
                 can write
                     "yes"

我花了一段时间才弄明白为什么我看到套接字说“can read=yes”，而错误消息说它不可读。事实证明，在执行

load（）

时，连接被gzcon对象包装。如果我自己包装，我会看到：

> s <- socketConnection(host = "localhost", 12345, server = FALSE, blocking=TRUE, open = "rb")
> s
        description               class                mode                text
"->localhost:12345"          "sockconn"                "rb"            "binary"
             opened            can read           can write
           "opened"               "yes"               "yes"

> s
        description               class                mode                text
"->localhost:12345"          "sockconn"                "rb"            "binary"
             opened            can read           can write
           "opened"               "yes"               "yes"
> z <- gzcon(s)
> z
               description                      class
"gzcon(->localhost:12345)"                    "gzcon"
                      mode                       text
                      "rb"                   "binary"
                    opened                   can read
                  "opened"                       "no"
                 can write
                     "yes"
> s
               description                      class

                      mode                       text
                      "rb"                   "binary"
                    opened                   can read
                  "opened"                       "no"
                 can write
                     "yes"

gzcon将连接转换为不可读。

所以我的问题是，如何从套接字执行加载，或者如何强制gzcon使连接保持可读性？

那么您是R新手，您要做的第一件事就是玩套接字？这似乎相当不寻常。你在这里的最终目标是什么？是的。对R来说是新手，但获得了将工作区从一个进程转移到另一个进程的任务。
