What steps will reproduce the problem?
1. my.model <- PredictionApiTrain(data="MYPATH/MYFILE.csv", 
remote.file="gs://MYBUCKET/MYOBJECT")

What is the expected output? What do you see instead?
trained model my.model is expected, however, R returns 
Error in system(command = command, intern = TRUE) : gsutil not found
I installed gsutil as described at 
http://code.google.com/apis/storage/docs/gsutil.html, and can list my bucket 
using: python gsutil ls gs://MYBUCKET/MYOBJECT

What version of the product are you using? On what operating system?
R 2.11.1, Windows, Python2.7

What steps will reproduce the problem?
1. I upload train.csv to the appps bucket through 
https://sandbox.google.com/storage
2. my.model <- PredictionApiTrain(data="gs://appps/train.csv")

What is the expected output? What do you see instead?
output:

~/.auth-token does not exist, let's create one for you

(eg. [email protected]): Please input your password for this account
: Requesting Authentication from Google ClientLogin for user: 
Error en strsplit(url, "")[[1L]] : subíndice fuera de  los límites

The error doesn't let me introduce email and password. How do i do that?

What version of the product are you using? On what operating system?
R version 2.11.1, Windows


Please provide any additional information below.

What steps will reproduce the problem?
1. run PredictionApiTrain(data="MYPATH/MYFILE.csv") as in example, where 
MYPATH/MYFILE.csv is my local csv file for training;

What is the expected output? What do you see instead?
I expected to get the trained model my.model as in the example, however, I got 
Error in PredictionApiTrain(data = "test.csv") : 
'remote.file' should be character

What version of the product are you using? On what operating system?
R2.11.1, on Windows

Please provide any additional information below.
I checked the code PredictionApiTrain just now, at the beginning there are 
lines:
if (missing(remote.file) || !is.character(remote.file)) 
stop("'remote.file' should be character")
However, remote.file is an argument without default value, function (data, 
remote.file, verbose = FALSE).

What steps will reproduce the problem?
1.my.model <- PredictionApiTrain(data="gs://elong0527/language")
