我在R中写了一个非常基本的包.其实我跟着
this tutorial创建了一个基本的包.
我的包在linux上工作得很好.例如：
> install.packages("linmod",repos=NULL)
Warning in install.packages("linmod",repos = NULL) :
argument 'lib' is missing: using '/home/jpgoel/R/i486-pc-linux-gnu-library/2.9'
* Installing *source* package ‘linmod’ ...
** R
** data
** preparing package for lazy loading
** help
*** installing help indices
>>> Building/Updating help pages for package 'linmod'
Formats: text html latex example
** building package indices ...
* DONE (linmod)
> library(linmod)
> data(mod1)
> mod1
Call:
linmod.default(x = x,y = y)
Coefficients:
Const Bwt
-0.3566624 4.0340627
现在,我拿了我的“linmod”文件夹,将其复制到Windows XP,并尝试以下操作：
> install.packages("C:\\Documents\ and\ Settings\\foo\\Desktop\\linmod",repos=NULL)
Error in gzfile(file,"r") : cannot open the connection
In addition: Warning messages:
1: In unzip(zipname,exdir = dest) : error 1 in extracting from zip file
2: In gzfile(file,"r") :
cannot open compressed file 'linmod/DESCRIPTION',probable reason 'No such file or directory'
>
好的.所以我拿起那个文件夹并把它放到.zip文件中.然后我去了Packages – >从本地zip文件安装包…并选择我的包.
> utils:::menuInstallLocal() updating HTML package descriptions > library(linmod) Error in library(linmod) : 'linmod' is not a valid installed package
我被困了我的包没有任何本地代码(例如,没有扩展名用C编写)
