createProfile: Define user profile information
In USGS-VIZLAB/vizlab: Utilities for building online data visualizations

This creates a file that describes where necessary executables are located in order to run make. This sets up a template, it is necessary to fill in the missing information

1	createProfile(directory = "~/.vizlab", overwrite = FALSE)

directory

location to save the profile.yaml file. Though directory accepts any directory path, the only useful values are those that point to ~/.vizlab or code./vizlab at runtime. The default is recommended except when the system variable HOME differs between the current R session (try Sys.getenv('HOME')) and the bash session from which make will be run (open bash and try echo $HOME). This parameter should match the bash version at a minimum; it might also be useful to run createProfile() once for each possible value of HOME (see examples). Another option is "./vizlab" within the project directory for this particular visualization.

overwrite

logical. If the file exists, should it be overwritten?
