# Conditional Replacement

Hi everyone,

Below I am illustrating an example where I am wanting to replace my NA values with corresponding scores. I have provided a second table of what I am looking to accomplish. Risk 4 demonstrates where I have all NA values, which will not get replaced. Risk numbers 5 and 6 show that my data might not have five years for every risk. Risk 7 is a very rare example where I would be fine if we only develop a solution to the other risk numbers. Thanks.

Sorry, where is the second table?

Can you provide a reproducible example?

Sorry, my first post did not go as expected. Please try the following.

Original_Table <- data.frame(Risk = c(1,1,1,1,1,2,2,2,2,2,3,3,3,3,3,4,4,4,4,4,5,5,5,6,6,7,7,7,7,7),
Year = c(2015,2016,2017,2018,2019,2015,2016,2017,2018,2019,2015,2016,2017,2018,2019,2015,2016,2017,2018,2019,2017,2018,2019,2016,2017,2015,2016,2017,2018,2019),
