Question

How can I append rows to an R data frame

Answer 1

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)
