In bioDS/phyloRNA: Tools for phylogenetic analyses of scRNAseq data

A wrapper around the system2 function that raise an error if the external external command resulted in an error. See the link{system2} function for more information.

1	systemE(command, args, call = FALSE, dir = NA)

`command`	an external command to run
`args`	an arguments to the command
`call`	prints the command call, useful for debugging
`dir`	run the command in a target directory. Some external commands create output in the directory they are executed. This is often less than ideal and leads to an unwanted shuffling with files or increased complexity to accomodate to this behaviour.
