find_sas {SASmarkdown}

A helper function that seeks to locate your SAS executable.

Description

This function searches for recent versions of SAS (>= SAS 8), in some of the usual default installation locations.

This function is automatically invoked when the SASmarkdown library is attached - normally a user will not need to call this function.

In the event SAS is not found, you will have to specify the correct location yourself.

Usage

find_sas(message=TRUE)

Arguments

message

(logical) Whether or not to print a message when SAS is found.

Value

A character string with the path and name of the SAS executable.
