Note: This post got buried and I never posted it. I haven’t played with R in several months, so I’m not sure if this works anymore.

This assumes you have R downloaded and installed.

Download, install, and configure GSUtil (https://code.google.com/apis/storage/docs/gsutil_install.html)

Load R. You should see an ugly console :) In the window type

install.packages(c("RCurl", "rjson"))

You will be prompted to select a mirror; find something close to you and continue.

You might be frustrated that there’s no success message:

trying URL 'https://www.revolution-computing.com/cran/bin/macosx/leopard/contrib/2.13/rjson_0.2.5.tgz'
Content type 'application/x-gzip' length 133138 bytes (130 Kb)
opened URL
==================================================
downloaded 130 Kb

The downloaded packages are in
	/var/folders/I3/I3YZ8e5tGOK9CY9LQ98ix++++TI/-Tmp-//RtmpFrtdp3/downloaded_packages

However, if you fail there will be an error message:

> install.packages("seth", dependencies = TRUE)
Warning message:
In getDependencies(pkgs, dependencies, available, lib) :
  package ‘seth’ is not available (for R version 2.13.0)
> install.packages("googlepredictionapi_0.1.tar.gz", repos=NULL, type="source")
Warning: invalid package ‘googlepredictionapi_0.1.tar.gz’
Error: ERROR: no packages specified
Warning message:

Download the Google Predictions API for R

https://code.google.com/p/google-prediction-api-r-client/

Install it

$ mkdir -p ~/R/library
$ mv googlepredictionapi_0.1.tar.gz ~/R/library/
$ R_LIBS_USER="~/R/library"
$ echo 'R_LIBS_USER="~/R/library"' >  $HOME/.Renviron
R CMD INSTALL ~/R/library/googlepredictionapi_0.1.tar.gz


Source your libraries


library(rjson)
library(RCurl)
library(googlepredictionapi)

  • If the data is already in your Google Storage account, you can begin training the model. I do not have data in GS yet, so I’ve stopped here.
