Re: [R] Error: argument is of length zero

I would assume that valsum is of zero length: > valsum <- numeric(0) > str(valsum) num(0) > if (valsum == 1) 1 Error in if (valsum == 1) 1 : argument is of length zero check your objects with 'str' On Thu, May 28, 2009 at 6:39 PM, Derek Lacoursiere wrote: > Hi, > > I have the following: > >

[R] Error: argument is of length zero

Hi, I have the following: for(j in (y.raw+1):(rownum-1)){ valsum<-tstfframed[min.x,j]+tstfframed[min.x,j+1] if(valsum == 1){ cat("valsum loop") int.num<-int.num+1 } }
