Hi,
I am creating a function and ran into the problem of selecting a column
from a dataset. It seems as though the $ function (as in data$columnname)
does not apply in the function. In simplified version:
This works:
testf2<-function(data,columnnumber){print(data[,columnnumber])}
But this doesn't:
testf<-function(data,column){print(data$column)}
Even though the first solution works, I would like to be able to insert the
columnname in the function, instead of the columnnumber. How do I do that?
Thank you in advance,
Julia
