It`s probably an easy question, but couldn`t figure it out.
I`ve defined a function like:
rmse<-function (x){
dquared<-x^2
sum1<-sum(x^2)
rmse<-sqrt((1/length(x))*sum1)
rmse}
My problem is, that I have NA Values in x and the above function returns NA.
I`m looking for a way to use "na.rm=TRUE" like in for instance
mean(x,na.rm=TRUE).
Does anybody know how to do this?
Thank you very much.
Mauro
