Re: [R] Error with toString
What packages are loaded? On the basic system, it works fine:
toString(123)
[1] 123
toString(c('a', 'b', 'zz'))
[1] a, b, zz

Re: [R] Error with toString
Anna, Try omitting pkg:RBloomberg. If you really need to use that package, you will have to install the non-CRAN package RDCOMClient from omegahat.

Re: [R] Error with toString
I don't think that rJava has a toString function. It does use
the function in base. I see a function toString.XMLNode() in
the XML package which is used as toString(x), so maybe that's
where your problem lies; but I didn't see the XML package in
your list of attached packages.
Anyway, here are two suggestions:
1. to answer your question directly: use
base::toString(x)
to enforce use of that function.
2. try
methods('toString')
to see what other toString()'s you may have around.

Re: [R] Error with toString
You have another toString function hanging around.
Your result is exactly what I get from methods('toString')
after I define
toString - function(x) x
You could try
getAnywhere('toString')

Re: [R] Error with toString
Ok Peter I think you were right about pointing out the RBloomberg package
because here is what I get with getAnywhere('toString'):
2 differing objects matching ‘toString’ were found
in the following places
package:RBloomberg
package:base
namespace:base
Use [] to view one of them

Re: [R] Error with toString
name toString(20)
is from Excel or OpenOffice; means 'logical and' in R, not string
concatenation.
paste() is simpler; sprintf() is more precise as to decimal places and
format.
