[R-SIG-Finance] access to real time market data

[babel at centrum.sk]

Hi guys
Are there a way how to access real-time market data (tick data, 1 minute data) for free in R? I know there are packages like RBloomberg or iBrokers but dont they depends on their commercial platform where you need to pay for account? Can I download real-time data,for example in quantmod, without paying for it? Thanks in advance
