Problem with initGRASS

Hi everyone,

I'm trying to use GRASS in R, but I can't get to initialize it. I'm using
Ubuntu 18.04 and GRASS 7.4.2. This is the system information:

Versi?n de GRASS: 7.4.2

Revisi?n SVN de GRASS: exported

Fecha de compilaci?n: 2018-10-28

Construir plataforma: x86_64-pc-linux-gnu

GDAL: 2.2.3

wxPython: 3.0.2.0

I'm running: > initGRASS(gisBase="/usr/lib/grass74/bin",override=T)
And this is the error:

sh: 1: g.gisenv: not foundsh: 1: g.gisenv: not foundsh: 1: g.gisenv:

I verified that g.gisenv and g.version are located in /usr/lib/grass74/bin.
Any suggestion?

Thanks in advance.

Best,

Jaime.
