Uma pergunta semelhante em AU - Instalando a última versão do R-base
O guia do CRAN sobre atualização no ubuntu - link
Eu estou supondo que há algumas suposições gerais que eu estou perdendo nas instruções que eles estão dando, porque eu estou saindo perdida.
Estou correndo 12.04 então saindo do guia do CRAN se eu colocar
deb http://cran.rstudio.com/bin/linux/ubuntu quantal/
em /etc/apt/sources.list ? Pode ir em qualquer linha vazia ou há uma ordem que eu preciso seguir?
Quando eu sigo o próximo passo no guia CRAN, eu faço uma atualização e instalo. Estou seguindo o guia como eu o entendo, mas há 'cardos em minhas meias'. Eu não sei o que está errado. Eu ainda estou carregando para 2.14 quando eu carrego em R.

Parece que a resposta à minha primeira pergunta é sim, basta colocar a linha em qualquer parte do documento em sua própria linha.
E embora eu não tenha um bom conhecimento de como isso funcionava, siga as etapas do link funcionou para mim.
Eu então tive um problema com o funcionamento dos pacotes de dependências que você pode ler em: link
