Hi, we had the following exercise and it worked well till last rbind. I have the following warning. Can you help to figure it out? Thank you. Error in match.names(clabs, names(xi)) : names do not match previous names name <- c("Flipper", "Bromley", "Nox", "Orion", "Dagger", "Zizi", "Carrie")mo <- c(53, 19, 34, 41, 84, 140, 109)size <- c("medium", "small", "medium", "large", "small", "extra small", "large")weight <- c(21, 8, 4, 6, 7, 2, 36)breed <- c("dog", "dog", "cat", "cat", "dog", "cat", "dog") pets <- data.frame(mo, size, weight, breed)names(pets) <- c("Months old", "Size", "Weight", "Breed")rownames(pets) <- namepets vaccinated <- c("Yes", "Yes", "No", "Yes", "No", "No", "Yes")petsv <- cbind(pets, "Vaccinated" = vaccinated)petsv milo <- data.frame(row.names = "Milo", Months.old = 67, Size = "small", Weight = 7, Breed = "dog", Vaccinated = "Yes")petsvm <- rbind(petsv, milo)petsvm

As the error message indicated, the column name that you want to rbind (Months.old) is different from the main column name (Months old).

Hi Joonseok, when defining name, the space is allowed like "Months old" names(pets) <- c(“Months old”, “Size”, “Weight”, “Breed”). when define a row with name, the space is not allowed, like Months old milo <- data.frame(row.names = “Milo”, Months old = 67, Size = “small”, Weight = 7, Breed = “dog”, Vaccinated = “Yes”). so How can we keep the name with space if I want to add a row as in this example?
