Question

I'm trying to install Ehrlinger's l2boost from github. I've tried using:

> library(devtools)
> install_github('l2boost',username='ehrlinger')

This gives the following output:

Installing github repo(s) l2boost/master from ehrlinger
Installing l2boost.zip from https://github.com/ehrlinger/l2boost/archive/master.zip

** help
No man pages found in package  'l2boost' 
*** installing help indices

** testing if installed package can be loaded

* DONE (l2boost)

The only error I notice is that it didn't find any help / man pages. However, it doesn't appear to have actually installed any of the functions:

> library(l2boost)
> predict.l2boost
Error: object 'predict.l2boost' not found

In C:\Program Files\R\R-2.15.3\library\l2boost\R, there are only three files: l2boost, l2boost.rdb, and l2boost.rdx. The l2boost\data folder atleast successfully installed diabetes.rda.

Why is neither the help nor the functions being installed? Is it possible to install this package using install_github?

Was it helpful?

Solution

I don't know exactly why the man pages aren't working but if you type

l2boost:::predict.l2boost

you will see the function. Here is an example (which should work) from the function definition available on github.

data(diabetes)
object <- l2boost(diabetes$x,diabetes$y, M=1000, nu=.01)
prd <- predict(object)
