Why is library(Seurat) causing my R session to have a fatal error? I recently tried to load library(Seurat) after installing Seurat package. It caused my R studio to have a fatal error and abort my session. I have successfully downloaded it before. I have uninstalled R and R studio and reinstalled, restarted my computer. I am new to R too, so I'm not sure what I'm doing. 

I am following the directions provided on the satijalab.org website on how to install Seurat. 

Here's a screenshot of the error message. 

I ran install.packages("Seurat") in R. R is also crashing as soon as I run library(Seurat). Here's a screenshot right before I hit run, and when it crashes, R application just closes.
If you haven't already done so I would make a complete installation of Anaconda, particularly good with bash. The I would either install using Anaconda Navigator, or ...

# Create an R environment and activate it
conda create -n r_env r-essentials r-base python=3.7
conda activate r_env

# install Reurat
conda install -c bioconda r-seurat

# installing standard packages
conda install -c r r-randomforest --yes


If you have a Mac the instructions are here. In some systems you need to just activate r_env . 

Please note if you've installed e.g. python3 with pip a conflict occurs with the Anaconda package.
