PCA with NA
...et with a lot of Na?s in it. So many, that
it is not possible to delete all rows with NA?s and also not
possible, to delete all variables with NA?s.
Is there a function for a principal component analysis, that can deal
with so many NA?s.
Thanks in advance

Is there perhaps a possibility to give the diagonal as a vector

I would be glad if somebody could help me.

Repeat if
...ng, because in this syntax i is not known
as a variable. But I don´t know how to say that it is a variable here.
Would be nice if somebody could help me.
Perhaps I´m thinking too complicated and there is an easier way to do
this.
Thanks in advance

Count data in random Forest
...)
I try to find the most important variables to divide my dataset as
given in a categorical variable using randomForest.
Is randomForest() able to deal with count data?
Or is there no difference because only the ranks are used in the trees?
Thanks in advance

randomForest and ordered factors
...TRUE, ntree=10000, do.trace=1000,

My dataset contains also ordered factors classified as such.
Is randomForest able to deal with it, does it change anything or is
there no difference in using factors or ordered factors?
Many thanks in advance
