I am particularly new to R - and subsequently drenched in red ink error stains.
However, I wanted to ask if someone could help with a package known as ValueEQ5D:
Most specifically, I am trying to carry out the the function 'map 5L to 3L'. https://www.rdocumentation.org/packages/valueEQ5D/versions/0.6.1/topics/map_5Lto3L
Basically, what this means is that health scores were measured in 5 levels, and I would like to map these to 3 levels, in terms of data reduction.
However, when I load in my Excel sheet and follow the R code, I get persistent error terms such as:
'Could not find function' (referring to my data)
'Column names do not match' (despite my columns having the same name as the commands)
'argument missing' (it says 'mobility' is missing with no default).
Would genuinely appreciate if someone has ran this set of commands before to show me an example of how they've done so, and what their Excel sheet looks like in preparation for the operation.
