Changing column names of a data frame
The error is caused by the "smart-quotes" (or whatever they're called). The lesson here is, "don't write your code in an 'editor' that converts quotes to smart-quotes".
names(newprice)[1]<-paste(“premium”) # errornames(newprice)[1]<-paste("premium") # worksAlso, you don't need paste("premium") (the call to paste is redundant) and it's a good idea to put spaces around <- to avoid confusion (e.g. x <- -10; if(x<-3) "hi" else "bye"; x).
