Hi everyone, I am sure that this question has been asked here some time ago but I do not remember the answer and was unable to find it in the archives...
Below is my question: suppose that I have a data.frame x and one of it's columns name is "CPI/RPI" (without quotation marks of course). How can I reference this column? Neither of x$CPI/RPI or x$"CPI/RPI" work. I certainly can do x[,which(colnames(x) == "CPI/RPI")] but there should be a nicer way to do this. Thank you!
