Potential bug in fitted.nls
...a single parameter is length 1, but if I multiply that constant by a
vector of ones, then the fitted values are of `length(y)`. Is this
something that should be reported?
``` r
dat <-
data.frame(y=c(80,251,304,482,401,141,242,221,304,243,544,669,638),
ones = rep(1, 13))
mNull1 <- nls(y ~ a, data=dat, start=c(a=mean(dat$y)))
fitted(mNull1)
#> [1] 347.6923
#> attr(,"label")
#> [1] "Fitted values"
mNull2 <- nls(y ~ a*ones, data=dat, start=c(a=mean(dat$y)))
