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
