如何将R对象的定义导出为纯文本,以便其他人可以重新创建它? [英] How to export the definition of an R object to plain text so that others can recreate it?
问题描述
在一个名为site.data的数据框中
> site.data
网站年度峰值
1 ALBEN 5 101529.6
2 ALBEN 10 117483.4
3 ALBEN 20 132960.9
8 ALDER 5 6561.3
9 ALDER 10 7897.1
10 ALDER 20 9208.1
15 AMERI 5 43656.5
16 AMERI 10 51475.3
17 AMERI 20 58854.4
如何打包,以便用户可以根据您的需要重新创建数据?
如果没有人下载文本文件并将其导入,您可以这样做。
(注意:这些数据是从REvolutions博客的一个例子中分析的)
dput命令写入ASCII表示。如果不是一个文件名,你会把它写入控制台。
> dput(site.data,)
structure(list(site = structure(c(1L,1L,1L,2L,2L,2L,3L,
3L,3L),.Label = c (ALBEN,ALDER,AMERI),class =factor),
year = c(5L,10L,20L,5L,10L,20L,5L,10L,20L) c(101529.6,
117483.4,132960.9,6561.3,7897.1,9208.1,4366.5,51475.3,
58854.4)),.Names = c(site,year,peak),行。 name = c(1L,
2L,3L,8L,9L,10L,15L,16L,17L),class =data.frame)
只需复制结构并将其放在示例代码中的site.data =之后,人们将能够完全按照您的要求重新创建数据框。 p>
Let's say you have this data in R, and you want to post a question on stackoverflow. For others to best help you, it would be nice if they could have a copy of your object (dataframe, vector, etc) to work with.
Let's say your data is in a data frame called site.data
> site.data
site year peak

How do you package it up so that the users can recreate the data exactly as you have it?
You want to do this without having people download a text file and import it.
(Note: These data subsetted from an example of the REvolutions blog)
The dput command writes an ASCII representation. If instead of a filename you put "" it will write it to the console
> dput(site.data,"")
structure(list(site = structure(c(1L, 1L, 1L, 2L, 2L, 2L, 3L,
3L, 3L), .Label = c("ALBEN", "ALDER", "AMERI"), class = "factor"),
year = c(5L, 10L, 20L, 5L, 10L, 20L, 5L, 10L, 20L), peak = c(101529.6,
117483.4, 132960.9, 6561.3, 7897.1, 9208.1, 43656.5, 51475.3,
58854.4)), .Names = c("site", "year", "peak"), row.names = c(1L,
2L, 3L, 8L, 9L, 10L, 15L, 16L, 17L), class = "data.frame")
Just copy the structure and put it after "site.data=" in your example code and people will be able to recreate the data frame exactly as you have it.
