Instalación kernel de R

Se siguen las instrucciones de instalación encontradas en este enlace irkernel.

Siendo root en deimos:

# /opt/tljh/user/bin/conda install r
# /opt/tljh/user/bin/conda install r-essentials


# R
> install.packages('IRkernel')
> IRkernel::installspec(user = FALSE)

En una sesión de jupyter, arriba a la derecha en 'new' aparece 'R'.

Instalación desde un entorno de mamba

# cd /opt/conda/mamba/
# mkdir Rnew
# cd Rnew
# /opt/conda/mamba/DE-global_hackathon/miniconda3/bin/mamba create -n Rnew -c conda-forge r-base
# eval "$(/opt/conda/mamba/DE-global_hackathon/miniconda3/bin/mamba shell hook --shell bash)"
# mamba activate Rnew
(Rnew) # which R
/opt/conda/mamba/DE-global_hackathon/miniconda3/envs/Rnew/bin/R

Instalando los paquetes para poder activarlo desde jupyterHUB

# R
> install.packages("IRKernel")
> system.file('kernelspec', package = 'IRkernel')
[1] "/opt/conda/mamba/DE-global_hackathon/miniconda3/envs/Rnew/lib/R/library/IRkernel/kernelspec"
> quit()
