Dear Members,
I get an error when I used ordiR2step command in "Vegan". However, same command is work for another dataset. 

nsk.rda.forward <- ordiR2step(rda(sp.h~1, data=env_d, scale=F), scope=formula(nsk.rda.all), direction="forward", pstep=100, perm.max = 1000)


## error
Error in eval(expr, envir, enclos) : could not find function "Condition"


Information about the two matixes are as follows; 
> dim(sp.h)

[1] 718 171


> dim(env_d)

718  65


Much appreciated if any one tell me how to fixed this issue. 

Thanks
