[R-br] ERRO ao instalar pacote rJava

[Emerson Cotta Bodevan]

Prezados,

minha intenção é instalar o pacote speedR. No entanto, ao tentar
instalá-lo, aparece a mensagem de que está faltando o rJava.

Bom... ao tentar instalar o rJava aparece a mensagem abaixo:

Make sure R is configured with full Java support (including JDK). Run

If you don't have root privileges, run
R CMD javareconf -e
to set all Java-related variables and then install rJava.

Alguém sabe como resolver? Agradeço qualquer ajuda.

Atenciosamente,
Emerson.

OBS.: ao tentar instalar o speedR e o rJava, eu rodava o R como "sudo". Uso
o ubuntu.
