How can a add a row to a data frame in R?

How can a add a row to a data frame in R?

In R, how do you add a new row to a data frame once the data frame has already been initialized?

So far I have this:

df <- data.frame("hi", "bye")

names(df) <- c("hello", "goodbye")



#I am trying to add "hola" and "ciao" as a new row

de <- data.frame("hola", "ciao")



merge(df, de) # Adds to the same row as new columns



# Unfortunately, I couldn't find an rbind() solution that wouldn't give me an error

Any help would be appreciated

Hence, you need to explicitly declare the columns names for the second data frame, de, then use rbind(). You only set column names for the first data frame, df:

df<-data.frame("hi","bye")

names(df)<-c("hello","goodbye")



de<-data.frame("hola","ciao")

names(de)<-c("hello","goodbye")



newdf <- rbind(df, de)

Let's make it simple:

df[nrow(df) + 1,] = c("v1","v2")
