[R-sig-Epi] Optmatch Package Question

[bh1 at me.com]

Hello , 

My optmatch package is loaded on R and otherwise running fine. 
I get an error after lcds successfully completes a logistic regression and 
I then try to obtain a propensity score: 

pdist <- pscore.dist(lcds) 
Error: could not find function "pscore.dist" 

Since pscore.dist is part of the optmatch package, 
does anyone know why this command would fail to run
pscore.dist ? 
I searched the help files, other online sources, could find no answer for 
this. Any advice would be greatly appreciated! 

Thank you ,
