I'm very new to R and I'm trying to clean my data for processing. I have a column (factor variable) that contains time information in the following format:
`1H 35MIN 37SEG`

Before I proceed to convert this into time, I'd like to convert all my observations from the above format, I need to eliminate the letters and the spaces, such that I have all my observations like this instead:
`1:35:37`

Any idea how I can do this?

Thanks
