How can I append rows to an R data frame

You can quickly append one or more rows to a data frame in R by using one of the following methods: Method 1: Use rbind() to append data frames. Method 2: Use nrow() to append a row.

Consider a dataSet i.e cicar(present under library MASS)

In order to load the dataset type following commands in R console

>library(MASS)

>cicar

So you have loaded dataset, cicar which is as follows:

Sex Bwt Hwt

1 M 3.0 7.0

2 F 2.0 8.4

3 F 1.0 9.5

To add new Row

1) First create new row for dataFrame

> nRow <- data.frame(Sex=’F’,Bwt=2.1,Hwt=8.1)

>cicar <- rbind(cicar,nRow)
