R: Error in install.packages : cannot open the connection

问题

I was trying to install the package RINDSEL but I am unable to install it and I keep getting the following error:

Error in install.packages : cannot open the connection

I downloaded the package from:

rindsel_1.0_2.zip | Integrated Breeding Platform

and loaded it from the directory. Other packages from the directory can be installed but just not this one.

Is the package corrupt or could there be any other error?

I would really be grateful for any help. Thanks in advance

回答1:

Rename the zip file RinSel Software into Rindsel. That's the name specified in the discription file.

Then, you can install the package in R with the command

install.packages("C:/path/to/Rindsel.zip",repos=NULL,type="win.binary")

That works fine... at first (!!!).

Problem with the Rindsel package is. It is quite old. It was build with R 2.13.1. Therefore, if you want to load the library which would be the next step to use the package in R you will get the error:

Problems building package (Error: "package has been build before R-3.0.0")

My suggestion: Contact the authors of the package and ask them if they can either provide the source file that you can build the package by yourself or if they can bundle the Rindsel package with a newer R version.

(Or you could try to hunt down an old R version and see if you can get the thing running with an old R... However, I would not seriously suggest to do that. It would probably result in conflicting dependencies with the other required packages...)

EDIT 15-02-2018: OP asked if one can build an R package with sources that are presumeably the Rindsel source files.

Yes, basically, you could do that. You would have to make a your own description and namespace file and put the source file in the R folder than invoke the command in R to build it....

But it's not neccessary with the script files provided by the link the OP posted.

OP, just run the scripts in R! It's quite easy.

Download the zip-file and extract it on your machine.
Go to that directory. The R command would be

setwd('path/to/your/directory')

Than run the R script, e.g, the KNIndex.r. It's simple:

source('KNIndex.r')

Then the script will run and produce some output / prompts.

回答2:

For future readers, I was able to fix the error by running RStudio with administrative privileges to get the command to work.

If that does not fix it, you might wish to try

Installing "r tools" if that is not installed already. That can be downloaded from https://cran.r-project.org/bin/windows/Rtools/
Download a relevant package that you are trying to install (e.g., tidyverse_1.3.0.zip) from https://cran.rstudio.com/
and install that from local path
It can also be installed directly from the web using install.packages("https://cran.rstudio.com/bin/windows/contrib/4.0/tidyverse_1.3.0.zip")
