As your experience grows, you will be able to adjust your speed to that of oncoming vehicles when turning right, so that you should be able to turn in without stopping (depending on the level of traffic) by either passing before or after an oncoming vehicle.
Building the skill of assessing approach speeds of other vehicles takes time. if you are unsure whether you will be capable of crossing into the junction without affecting oncoming vehicles, then wait until there is a bigger gap. Generally, the skills you learnt as a pedestrian are no different, and as long as you have good clutch control it will take very little time to become fluent with turning right.
