Dear all,
I have a problem with the knn's function in EMV package.
When I try to do like the example given in help Html it works, but with
my own matrix, R returns the following message :
> library (EMV)
> temp [1:3, 1:10]
V3 V4 V5 V6 V7 V8 V9 V10 V11 V12
3 -0.03 -0.29 0.12 -0.05 -0.12 0.02 -0.17 0.09 0.29 -0.04
4 -0.25 -0.36 -0.29 -0.21 -0.15 -0.15 NA -0.13 0.16 -0.09
6 -0.40 -0.37 -0.39 NA -0.13 -0.22 0.01 -0.15 -0.22 NA
> matcomplete <- knn(temp,k=15)
Error in knn(temp, k = 15) : No rows without missing values
My matrix has actually 14% of NA, which are recognized by R as NA
(summary function). My matrix (temp) is in a numeric mode and has
dimension of 3169*160
Is anybody has the same problem or knows a solution?
Thanks.
Alice.
