Static variable next to a dynamic variable in R
I posted yesterday another question but I feel I need to clarify it.
Let's say I have this code
md.NAME <- (subset(MyData, HotelName=="ALAMEDA"))
md.NAME.fc <- (subset(md.ALAMEDA, TIPO=="FORECAST"))
md.NAME.fc.bar <- (subset(md.ALAMEDA.fc, Market.Segment=="BAR"))
What I want is that NAME changes according to a variable set before those 3 lines are run,
So NAME is just dynamic in the sense that before these 3 lines I could say, ok, NAME now is equal to JOHN, but then, I could say that NAME is now equal to PATRIC.
So after running those 3 lines, twice (once for John and once for Patric) somehow in the environment I will get something like this:
6 dataframes, 3 for JOHN and 3 for PATRIC
DATAFRAME 1 WILL BE md.JOHN
DATAFRAME 2 WILL BE md.JOHN.fc
DATAFRAME 3 WILL BE md.JOHN.fc.bar
DATAFRAME 1 WILL BE md.PATRIC
DATAFRAME 2 WILL BE md.PATRIC.fc
DATAFRAME 3 WILL BE md.PATRIC.fc.bar
All the answers I had so far would help me only if "md" and "fc" or "fc.bar" are always the same. But I will have several variables like this, which will change a lot as far as the naming goes. So, it is the center part (NAME) the only one that should change.
I could even have something like:
md.test$NAME <- ...

Instead of creating objects in the global env, place it in alistand then chang thenameof thelisti.e.lst1 <- mget(ls(pattern = "^md.NAME"))

Theassign()function could be helpful. Something likeassign(paste0("md.", NAME), value=subset(MyData, HotelName=="ALAMEDA"))- To get more precise answers please provide a reproducible example.

Yesterday you were advised that this was a bad idea. It still is.
