D帧到R [英] Deedle frame to R
问题描述
我正在使用 rinterop 作为参考。
我有一个框架< DateTime,string>
,我尝试使用
$ b $发送给R b
let frame =
let aSerie =
Series.ofObservations
[ DateTime(2013,1,1)=> 10.0
DateTime(2013,1,4)=> 20.0
DateTime(2013,1,8)=> 30.0]
框架([Hello],[aSerie])
R.as_data_frame(frame)
其中给出以下内容:
System.Exception:没有转换器注册类型
Deedle.Series `2 [[System.DateTime,mscorlib,Version = 4.0.0.0,
Culture = neutral,PublicKeyToken = b77a5c561934e089],
我还尝试了以下示例:
let rnd = Random()
让ts =
[for i in 0.0 .. 100.0 - >
DateTime.Today.AddHours(i),rnd.NextDouble()]
|>系列
R.as_zoo(ts)
导致相同类型的错误: / p>
System.Exception:没有转换器注册类型
Deedle.Series`2 [[System.DateTime,mscorlib,Version = 4.0 .0.0,
Culture = neutral,PublicKeyToken = b77a5c561934e089],[System.Double,
mscorlib,Version = 4.0.0.0,Culture = neutral,
PublicKeyToken = b77a5c561934e089]]或其任何基本类型
我的最终目标是绘制Deedle框架,使用 DateTime
使用R的行键。
我认为FsLab中的安装脚本有一个错误 - 你能检查一下文件 Deedle.dll
和 Deedle.RProvider.Plugin.dll
(隐藏在 packages
文件夹)被复制到 RProvider.dll
生活的目录(即 packages\RProvider.1.0.5\ lib
)。
如果不,复制文件是否解决问题? (假设文件不存在,并将它们复制到目录中可以解决问题,这看起来像是FsLab的安装脚本中的错误。)
I am trying to put some code to work. I am using rinterop as a reference.
I have a Frame<DateTime,string>
which I try to send over to R using
let frame =
let aSerie =
Series.ofObservations
[ DateTime(2013,1,1) => 10.0
DateTime(2013,1,4) => 20.0
DateTime(2013,1,8) => 30.0 ]
Frame(["Hello"], [aSerie])
R.as_data_frame(frame)
which gives the following:
System.Exception: No converter registered for type Deedle.Series`2[[System.DateTime, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089],
I also tried the following example:
let rnd = Random()
let ts =
[ for i in 0.0 .. 100.0 ->
DateTime.Today.AddHours(i), rnd.NextDouble() ]
|> series
R.as_zoo(ts)
which result in the same kind of error:
System.Exception: No converter registered for type Deedle.Series`2[[System.DateTime, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089],[System.Double, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089]] or any of its base types
My ultimate goal is to chart Deedle frames, with DateTime
as row keys using R.
I think there is a bug in the installation script in FsLab - can you please check that the files Deedle.dll
and Deedle.RProvider.Plugin.dll
(hidden somewhere in the packages
folder) were copied to the directory where RProvider.dll
lives (that is packages\RProvider.1.0.5\lib
).
If no, does copying the files there resolve the issue? (Assuming the files are not there and copying them to the directory solves the problem, this looks like a bug in our installation script for FsLab.)
