R: use the package by unpacking it and not install it

Question

I am trying to use a package that cannot work with this in an Rgui window. On the website of the package it is proposed to unpack and use the function

http://mouse.cs.ucla.edu/emma/install.html

But I could not find where I can find the function that I can enter in my R console and use it.

RGUi that comes with the Windows distribution

Package Used: emma, can be downloaded from the website above.

Answer 1

And the all-R version, without a mouse (I was almost there Roman!):

download.file("http://mouse.cs.ucla.edu/emma/emma_1.1.2.tar.gz", destfile=paste(getwd(),"/emma/emma_1.1.2.tar.gz",sep="")) untar(paste(getwd(),"/emma/emma_1.1.2.tar.gz",sep=""), compressed = "gzip") source(paste(getwd(),"/emma/R/emma.R",sep="")) 

in which a new directory (emma /) will be created in your current working directory.

Answer 2

You can download the .tar.gz file and use the untar function. I moved the specified file to my Q drive in the emma folder and ran the following command. The result was extracted to a folder called emma in my working directory.

 untar("q:/emma/emma_1.1.2.tar.gz", compressed = "gzip") 

After you have done this, you can source .R files (see comments for your question).
