Hi,
I am applyin function as.numeric to a vector having many values as
NA and it
is giving :
Warning message:
NAs introduced by coercion
Can anyone help me to know how to remove this warning and sor it
out?
Let's say that the vector you are calling `as.numeric` over is called
`x`. If you could show us the output of the following command:
R> head(x[is.na(as.numeric(x))])
You'll see why you are getting the warning.
How you choose to sort it out probably depends on what you are trying
to do with your data after you convert it to a "numeric"

Hi,
I am having this error bacouse vector contains value NA but i want to
convert that vector to numeric
I don't quite follow what the problem is, then ... what is the end
result that you want to happen?
When you convert the vector to a numeric, the NA's that were in it
originally, will remain as NAs (but they will be of a 'numeric' type).
What would you like to do with the NA values? Do you just want to keep
them, but want to silence the warning?
If so, you can do:
R> suppressWarnings(y <- as.numeric(x))
