Hi Petr, 
Thanks for reply 

sorry for late message there was typo error the both values are -999.99 
 a[rowSums(a ==  -999.99) == 0, ], this solution works only if we have to
remove certain value from matrix. 

but if 
a<-matrix(c(1,2,3,5,-999.99,5,-999.99,6,1,5,9,1),nrow=4)  

a
     [,1]    [,2] [,3]
[1,]    1 -999.99    1
[2,]    2    5.00    5
[3,]    3 -999.99    9
[4,]    5    6.00    1

and I would like to remove whole row those have value -999.99 , this
particular function does not work
I got error 

Error in rowSums(a[, 2] == -999.99) : 
  'x' must be an array of at least two dimensions

 it need matrix, so is there any way to deal with this kind of problem. 


Cheers 
Uday
