Hi Michael.
This is a classic :-)
ObjectsOfInterest<- list(one_df, two_df, three_df)
for(namedf in ObjectsOfInterest){...}
or probably even better
sapply(ObjectsOfInterest, function(namedf){...})
hth.

Subject: [R] Reference variables by string in for loop
Dear R Users,
I am trying to get the following to work better:
namevec <- c("one", "two", "three")
for (name in namevec) {
namedf <- eval(parse(text=paste(name, "_df", sep="")))
...
...
}
The rationale behind it being that I created variables with names
one_df, two_df and three_df earlier in the same script which I want to
reference inside the for loop. Is there a more elegant way to do this?
Best Regards,
Michael Bach
