error message in plm

Hi everyone,

Could anyone tell me what means the follow error message

Error in xj[i] : invalid subscript type 'closure'

It happens when I run the function plm, like this:
ff<-totaccz~lactivoz+varvolnegz
ss<-plm(ff,data=regaccdis,na.omit)
Error in xj[i] : invalid subscript type 'closure'
coef(ss)
(Intercept)    lactivoz  varvolnegz
  0.02571212  6.94227541  0.10340165

Thank you,

A closure is a standard R function (that is not a primitive function).

This is presumably from package plm.  You called plm() with three 
arguments, that is subset=na.omit by the matching rules.  I think 
you intended na.action=na.omit.  na.omit is a 'closure'.
