Changing column names of a data frame

Question

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? Select the correct answer from above options

To change the column names of a data frame, you can use the colnames() function as follows: colnames(dataframe) <- c('premium','change','newprice') Output: premium change newprice 1 100 36 136 2 120 -33 87 3 150 14 164 To change the name of a particular column: colnames(dataframe)[2] <- "change"
