if statement problem

Hello,

I want to do fisher test for the rows in data file which has value less
than 5 otherwise chi square test .The p values from both test should be
stored in one resulted file. but there is some problem with bold if
statement. I don't know how 
implement this line properly.


x = cbind(obs1,obs2,exp1,exp2)
a = matrix(c(0,0,0,0), ncol=2, byrow =TRUE)        #matrix with
initialized values

for (i in 1: length(x[,1]))
{
      *if((x[i,1] || x[i,2] || x[i,3] || x[i,4]) < 5)*
