I'm trying grnn package, and reproduced the example (
http://cran.r-project.org/web/packages/grnn/grnn.pdf), I tried the example
with another x input column in the dataset (see below):
but I'm getting the following error "Error in Ya * patterns1 :
non-conformable arrays", though I took care to pass an input of length 2
n <- 100
set.seed(1)
x1 <- runif(n, -2, 2)
x2 = x1^2
y0 <- x1 * x2
epsilon <- rnorm(n, 0, .1)
y <- y0 + epsilon
grnn <- learn(data.frame(y,x1, x2))
grnn <- smooth(grnn,sigma=0.1)
guess(grnn, c(2,4))
*Error in Ya * patterns1 : non-conformable arrays*
guess(grnn, data.frame(x1=c(2), x2=c(4)))
*Error in (X - Xa) %*% t(X - Xa) : *
* requires numeric/complex matrix/vector arguments*
