Re: [Rpy] How can I append a vector to a matrix when the vector has more rows than the matrix?

[Laurent Gautier]

There is no "cbind.na" in a vanilla R install. May be this is a function 
coming with a package and it should be loaded because the function can 
be found by R ?

PS: I am not certain about the intent behind trying to "append a vector 
to a matrix when they have a different number of rows".

Hi everyone,

I want to append a vector to a matrix with different row lengths using 
the cbind.na <http://cbind.na> method from R. However, robjects 
doesn't find cbind.na <http://cbind.na>

    import rpy2.robjects as R
    R.r['cbind.na <http://cbind.na>'](matrix, vector)

gives a LookupError: 'cbind.na <http://cbind.na>' not found. Python 
docstrings only says:

cbind(/*args/, /**kwargs/)¶ 
<http://rpy.sourceforge.net/rpy2/doc-2.1/html/robjects.html#rpy2.robjects.vectors.DataFrame.cbind>

        bind objects as supplementary columns

And the only example I can find of using name*dot*name that I can find 
is about parameters, like this example:

     from  rpy2  import  robjects


     myparams  =  {'na.rm':  True}
     robjects.r.sum(0,  **myparams)

 So how can I append a vector of to a matrix when they have a 
different number of rows?

Thanks!
