Dear R users,
I'm trying to randomly recreate a real dataset with missing data and I'm
not quite sure if I can use the sample command for this. I think it
might be better to do it in 2 steps and randomly replace the sampled
data with missing data...
So something like this
x <- sample(10000:20000, 100) #without replacement
Now I want x to contain to 20% missing data (NA). Could anyone help me
how to do this?
Thanks
Joanne
