spip_exists {CKMRpop}

return TRUE if spip exists where it should be installed.

Description

This just checks for the file where it gets installed with install_spip(). This is exported so it can be used to control the flow in the vignettes, so that vignettes can still be written using saved results when spip is not installed (i.e., at CRAN, etc.)

Usage

spip_exists()

Value

A single logical scalar, either TRUE or FALSE.

Examples

# will be FALSE unless spip has been externally installed
spip_exists()
