How to install gcc-4.7-arm-linux-gnueabihf on Ubuntu 12.04?

Question

In an R data.frame I would to find the missing year by group and add a row for each missing year and repeat the last value.

An example

This is a data.frame

 1. GROUP/YEAR1/YEAR2/YEAR3
 2. A/100/190/na
 3. A/90/na/300
 4. B/200/70/na

I Want

1. GROUP/YEAR1/YEAR2/YEAR3
  2. A/100/190/190
  3. A/90/90/300
  4. B/200/70/70

Solution

Unexpectedly, I found a solution:

Add 13.10's apt source into /etc/apt/sources.list

deb http://cz.archive.ubuntu.com/ubuntu raring main universe

Then you can install it with

sudo apt-get install gcc-4.7-arm-linux-gnueabihf

@diego the updated dataset and expected output seems to have a typo - header has 4 columns but data has 5 columns. You may need to update the sample & expected dataset properly.

Regarding the EDIT you want the apply to only work on the numeric columns so I think you want this: library(zoo); replace(df, -1, apply(df[-1], 1, na.locf0)) .
