MLE error in R: initial value in 'vmmin' is not finite

Question

Suppose I have 2 data.frame objects:

df1 <- data.frame(x = 1:100)
df1$y <- 20 + 0.3 * df1$x + rnorm(100)
df2 <- data.frame(x = 1:200000         


        

Answer 1

known bug in R, bugzilla ID 17703. Notoriously difficult to reproduce.
