I have a data frame called "newprice" (see below) and I want to change the column names in my program in R.
> newprice
Chang. Chang. Chang.
1 100 36 136
2 120 -33 87
3 150 14 164
In fact this is what am doing:
names(newprice)[1]<-paste("premium")
names(newprice)[2]<-paste("change")
names(newprice)[3]<-paste("newprice")
I have not put this in a loop because I want each column name to be different as you see.
When I paste my program into R console this is the output it gives me:
> names(newprice)[1]<-paste(“premium”)
Error: unexpected input in "names(newprice)[1]<-paste(“"
> names(newprice)[2]<-paste(“change”)
Error: unexpected input in "names(newprice)[2]<-paste(“"
> names(newprice)[3]<-paste(“newpremium”)
Error: unexpected input in "names(newprice)[3]<-paste(“"
I have equally tried using the c() function-for example c("premium"), instead of the paste() function, but to no avail.
Could someone help me to figure this out?
